Breaking Down Mouthguard Buildup

January 7th, 2026

Mouthguards protect our oral health. They shield our teeth and mouths from injury during sporting activities, prevent damage from tooth grinding, and help treat sleep apnea. But sometimes, these hardworking tools need some TLC of their own. Read on to learn how to keep your appliance its sparkling, healthy best!

Mouthguard Buildup

You might notice after a few months of use that your guard is stained with white spots or a discolored film. Or that there are gritty patches on its smooth surface. Or you might suddenly notice an unpleasant odor.

If you’re wondering what’s happened to your once-pristine mouthguard, let’s break down the source of these stains, deposits, and odors.

  • Plaque is a mix of food particles, bacteria, and saliva which sticks to tooth enamel. If it’s not removed, plaque can harden into tartar. And, just like plaque and tartar stick to your enamel, plaque and tartar can transfer from the teeth and stick to your guard, leaving white spots or a discolored film.
  • Mineral deposits are another source of white spots and gritty buildup. Calcium and phosphate are two of the minerals found in saliva. They replace the calcium and phosphate minerals which have been stripped from tooth enamel by acidic foods or the acids created by plaque bacteria. And while these minerals are vital for enamel health, they’re not doing your mouthguard any favors! As saliva dries on your appliance, it leaves behind a residue of these white gritty minerals.
  • When food particles and plaque build up on teeth, they cause bad breath. When food particles and plaque build up on appliances, they cause an unpleasant odor.

Removing Retainer Buildup

How do we break down this buildup? There are some simple ways to reduce or remove plaque, tartar, and mineral accumulation when you’re taking care of your mouthguard:

  • Rinse off your guard as soon as you remove it from your mouth.
  • Clean your mouthguard every time you wear it with a soft-bristled toothbrush. Because even non-abrasive toothpastes can be hard on appliances, ask Dr. James Robson which toothpaste—if any—is best.
  • Regular deeper cleaning helps reduce the chance of buildup. Your dental team in Robson Dentistry in East Lyme, CT can suggest effective ways to get your guard its cleanest, with recommendations like a white vinegar/water soak or an over-the-counter cleaning product made for appliances. Deep clean weekly or monthly as needed.
  • Use cool or lukewarm water to clean or soak, because hot water can warp mouthguards.
  • Don’t forget to clean your case regularly, as it can also harbor plaque, minerals, germs, and food particles.

Prevention is best!

Of course, the very best way to reduce mouthguard buildup is to prevent it from accumulating in the first place.

  • Keep your teeth clean. When your brushing and flossing is on point, you’ll really reduce the amount of food particles and bacteria which transfer to your appliance.
  • If you can’t brush right away, rinsing with water after eating or drinking helps remove food particles and acids from the teeth. Water is also safe to drink with your appliance in place. Which leads us to . . .
  • Mouthguards aren’t meant for meals or beverages. Eating solid foods can damage a guard. Food particles stick to appliances. Clear plastic appliances which fit over the teeth can stain. And, because they fit closely over the teeth, these guards can trap foods and beverages next to your teeth, exposing your enamel to sugars and acids over a longer period. Place your guard in its case, enjoy your meal, and brush and floss as directed before your replace the appliance in your mouth.

A clean appliance is a healthy appliance! Keep your mouthguard—and your teeth and gums—in the best of health with simple, daily TLC.

Three Classic New Year’s Resolutions for Your Dental Health —and Three Which Might Surprise You!

December 31st, 2025

Whether you’re using the latest note-taking app or old-school pen and paper, it’s a good time to start jotting down your resolutions for a healthier, happier New Year. To help the process along, we have some suggestions for traditional tooth-friendly resolutions—and also some ideas which might surprise you!

The Classics

  • Brush and Floss Regularly

If you’re sticking to the “two minutes twice a day” brushing schedule as well as flossing once a day, great work! Often, though, that two-minute window starts to shrink as our brushing routine becomes *too* routine. Try timing yourself while you brush normally. If you’re falling quite a bit short of two minutes, taking just a bit more time will be lots more effective in removing plaque from your teeth.

And since gum disease is a leading cause of tooth loss in adults, commit to flossing once a day to remove irritating plaque and bacteria from between teeth and around the gumline.

  • Use Fluoride Toothpaste

Fluoride toothpaste doesn’t just help prevent cavities by cleaning away plaque and food particles. It also helps make our enamel stronger. 

Acids created by plaque bacteria and acids in our diet dissolve minerals from tooth enamel, making it softer and more vulnerable to cavities. Fluoride bonds with the minerals in enamel to create an even stronger protective enamel coating. Check with Dr. James Robson or the American Dental Association’s website for the best toothpaste choices for healthy, strong enamel.

  • See Your Dentist Regularly

Dentists typically recommend a full dental exam and cleaning twice each year. Your dental team at Robson Dentistry will take X-rays as needed, examine your teeth, gums, and general oral health, and screen for oral cancer. A professional cleaning will remove any built-up plaque and tartar, which is especially important for gum health.

Being proactive with your dental care means you’ll be sharing your healthy smile all year long—as well as discovering any potential problems before they can develop into major problems!

The Surprises

  • Chew (Sugarless) Gum

When you’re not producing enough saliva, you feel the effects of dry mouth, including sore throat, difficulty swallowing, and bad breath. Another side effect? Poorer dental health. 

Saliva helps neutralize the acidic foods we eat, washes away bacteria and food particles, and contains minerals like calcium and phosphorus which remineralize tooth enamel. Chewing sugarless gum encourages saliva production. If you suffer from dry mouth, check with your dentist to see if chewing sugar-free gum can help.

  • Don’t Brush Right After Eating

Brushing after a meal is great to remove food particles like sugars and carbs which stick to our teeth—and which the bacteria in plaque thrive on. But if you’ve been eating or drinking acidic foods, it’s best to wait about an hour before brushing. 

Acids in foods, like acids created by bacteria, weaken tooth enamel. Brushing right away can be abrasive and damage enamel, but if you wait for an hour, the minerals in saliva have a chance to remineralize and restore your enamel strength.

  • Toss Your Toothbrush

Not that we mean give up brushing altogether! But your toothbrush bristles start to fray and fan out after several months, meaning that you won’t be getting the full cleaning effects of your great brushing technique. Put a note on your calendar to replace your brush every three to four months for the best in plaque removal.

If you’re already following all these suggestions for protecting your dental health, resolve to keep up the good work! If not, give these easy-to-follow recommendations a try. Protecting your dental health is essential to gift yourself a new year filled with happy, healthy smiles in East Lyme, CT.

Sensitive Information

December 24th, 2025

Psst—here’s some time sensitive information just for you. If your teeth are sensitive to heat, cold, sweets, acidic foods, wind and/or air, it could mean it’s time to see Dr. James Robson!

Normally, we don’t notice how external conditions affect our teeth at all. Tooth enamel—the hardest substance in the body—protects the inner tooth from outside stimuli. So, why do strong, solid teeth suddenly feel sensitive? The answer’s found in tooth anatomy.

The crown of the tooth, the part we can see above the gum line, has three distinct layers.

  • Enamel, a strong mineral-rich coating, surrounds the outside of each tooth and protects the dentin and pulp inside.
  • Dentin is the softer, porous middle layer of the tooth. Dentin contains thousands of tiny, fluid-filled tubules which extend to the pulp.
  • In the center of each tooth is the pulp chamber, filled with nerves, blood vessels and connective tissue which keep the tooth alive and healthy.

The roots below the gumline have a similar structure, with one important exception.

  • Cementum, which is not as hard and strong as enamel, covers the root surface instead of enamel.

Healthy, undamaged teeth allow you to enjoy an icy beverage, a hot latte, a sweet treat, or a brisk walk without any dental discomfort.

When the tooth’s protective enamel covering is worn or damaged, the dentin below the enamel is exposed to external conditions. Temperature changes, air, wind, sweets and acids—all the stimuli which normally have no effect on our teeth are now transmitted through the dentin’s tubules to the nerves inside the pulp.

The pulp’s nerves respond to these sensations by sending out pain signals. The uncomfortable tooth sensitivity which results is often described as an annoying twinge, a sharp, brief stabbing pain, or a shocking sensation.

There are several potential causes of dentin exposure, including:

Aggressive Brushing

Brushing is great! Over-aggressive brushing? Not so much. Heavy-handed brushing can wear down mineral-rich tooth enamel and is even more damaging to less-mineral-rich cementum.

Dental Products

Some mouthwashes, rinses, and whitening treatments containing alcohol or bleaching agents can cause temporary sensitivity, especially when there’s exposed dentin.

Cavities and Damaged Restorations

The bacteria in plaque create acids which strip minerals from tooth enamel. Over time, a hole in the enamel develops, uncovering the sensitive dentin below. Similarly, when fillings or crowns loosen or suffer damage, the dentin surface underneath is exposed to air and temperature changes.

Injuries

A crack or fracture can expose dentin, or, in severe cases, tooth pulp, to foods, heat, cold, and air.

Diet

An acidic or sugary environment in the mouth harms enamel. Consuming acidic foods and beverages erodes the minerals which make enamel so strong. Sugars give plaque bacteria the perfect fuel for producing their enamel-eroding acids.

Tooth Grinding

Bruxism, or tooth grinding, often takes place during sleep, and can apply over a hundred pounds of pressure to the teeth and jaws. Continuous grinding and clenching wears away tooth enamel, exposing dentin. Bruxism can also cause chipped and cracked teeth, as well as jaw damage and even tooth loss.

Malocclusion

Occlusion refers to the way our teeth and jaws fit together. In a healthy occlusion, the forces of biting and chewing are normal and evenly distributed. A malocclusion, or bad bite, can cause excessive or uneven pressure on teeth and jaws, leading to worn enamel, cracked teeth, and more serious bite problems.

Gum Disease

Gum disease can cause the gums to pull away from the teeth. This gum recession exposes the tooth’s root, which is covered with softer cementum, making it more vulnerable to sensitivity and decay.

Just as there are many causes for tooth sensitivity, your dental team at Robson Dentistry has many solutions to restore your comfortable, healthy smile.

Choose the Right Products to Protect Your Smile

  • If you’re not using a soft-bristled brush, trade in your old model ASAP, or try an electric toothbrush.
  • There are special toothpastes which are formulated to reduce sensitivity.
  • Talk to your dentist or hygienist at Robson Dentistry to learn the best ways to brush and the best products to use to protect your dental health and your tooth enamel.
  • Ask your dental team to recommend less acidic mouthwashes and whiteners designed for more sensitive teeth.

See Your Dentist Regularly

  • Regular exams will reveal any cavities before they become deeper and more damaging.
  • Dr. James Robson can set broken restorations to rights by creating a new filling or crown.
  • If you suspect you have an injured tooth, call our practice immediately to prevent more serious damage or infection.

Eat a Dental-Healthy Diet

  • Cut down on acidic and sugary foods.
  • Check ingredients. The amount of acids and sugars in foods like sodas and sports drinks could surprise you!
  • If you do eat something acidic, don’t brush right away—rinse with water and wait an hour to give your enamel time to strengthen and remineralize.

Protect Your Smile from Trauma

  • A custom-fitted nightguard can prevent enamel erosion and other damage caused by bruxism.
  • If you’re concerned about your bite, ask your dentist for an orthodontic referral.
  • Wear a mouthguard when playing contact sports or activities to protect your teeth from injuries.

Guard Your Gum Health

  • Regular exams and cleanings help prevent gum disease.
  • Bonding and sealers can be used to cover and protect exposed root surfaces.
  • Dr. James Robson might recommend periodontal treatments such as deep cleaning or gum grafting for more severe gum recession.

The first step in treating sensitivity is a visit to Robson Dentistry in East Lyme, CT to diagnose the source of your discomfort. Tooth sensitivity is time sensitive. Take care of small problems before they become serious ones, and you’ll help make sure your smile is something you’re not the least bit sensitive about!

Healthy Digestion Begins with Healthy Teeth

December 17th, 2025

You pay attention to what you eat. After all, your oral health depends on it. Without the necessary proteins, vitamins, and minerals in your diet, your teeth and gums will suffer. But did you know it’s a two-way street? Without healthy teeth and gums, your digestive system can suffer as well.

Because digestion doesn’t start in your stomach—it starts in your mouth! Let’s take a quick look at how the digestive system operates.

  • Teeth

The first step in digesting is breaking down foods so your body can extract their nutrients more easily. Healthy teeth are essential here. Incisors and canines tear food into smaller pieces while molars grind these pieces into an easy-to-swallow, paste-like consistency. While we chew, the surface area of the food increases, allowing the digestive enzymes in saliva, the stomach, and the small intestine to work more efficiently.

  • Salivary Glands

Saliva production increases when we eat. Digestive enzymes in saliva begin breaking down carbs into sugars, and separating fat molecules. Saliva also contains antimicrobial peptides which are important for oral and gut health.  

  • Esophagus

This muscular tube connects the back of the throat to the stomach. As we swallow, muscles in the esophagus contract and relax, an involuntary movement called peristalsis. These contractions push food down into the stomach. Peristalsis also occurs in the stomach and intestines, efficiently moving food through the rest of the digestive system. 

  • Stomach

Inside the stomach are gastric acids and enzymes which break food down further to help the small intestine make use of these nutrients in the next stage of digestion.

  • Small Intestine

This organ works to reap the benefits of our healthy diets. The small intestine absorbs about 95% of the nutrients from our digested food—carbohydrates, proteins, fat, vitamins, and minerals—and transfers these nutrients to the circulatory system to be used throughout the body. Any remaining food particles travel to the colon, or large intestine.

  • Large Intestine

Bacteria in the large intestine help process soluble fiber, which we can’t digest on our own. The large intestine is also where insoluble fiber and anything else undigested are converted to solid waste. 

Digestion begins in the mouth, and, when dental problems make chewing and swallowing difficult, the entire digestive system can be affected:

  • Uneven bite pressure

When you can’t apply chewing pressure because of decay, painful infections, or loose teeth, or when you are missing a tooth or teeth, it’s hard to chew food into the paste-like consistency necessary for rest of your system to process it smoothly.

  • Reduction in digestive enzymes and peptides

Saliva contains enzymes which make food easier to digest and antimicrobial peptides which are important for gut health. Xerostomia, or dry mouth, causes less saliva production. Inadequate chewing does as well. Without sufficient saliva, your system won’t benefit from the digestive prep work and gut protection which saliva typically provides. 

  • Uncomfortable swallowing

Insufficiently chewed food makes peristalsis in the throat and other digestive organs more difficult. Larger pieces of food can become stuck in the esophagus, causing painful swallowing or even choking. Dry mouth can also make swallowing very uncomfortable.

  • Higher risk of stomach problems

When food isn’t chewed thoroughly, the stomach has to work harder, and the risk of gastroesophageal reflux increases. Highly acidic gastric juices can back up into the esophagus and mouth, causing heartburn, chest pain, sore throat, and vomiting. 

  • Bowel irritation

When food particles are too large, the small intestine must work harder to break them down and to absorb their nutrients. Insufficiently digested food can upset the bacterial balance in the large intestine. These problems can cause indigestion, constipation, gas, and bloating.

  • Changes in nutrition 

Dental problems can also lead to nutritional imbalances even before we start to digest. Soft foods and liquids are often chosen over proteins, fruits, and vegetables when loose or missing teeth or painful teeth make chewing difficult. While a soft diet is fine for a few days if your mouth is a bit sore following dental treatment, it can be difficult to get the all the nutrients your body needs when you only eat soft foods.

Dentists generally recommend a thorough examination twice a year to discover and treat any oral problems before they become more serious, but any tooth pain or sensitivity is a good reason to see Dr. James Robson immediately. 

Whether you have a cavity, an infection, gum disease (one of the major causes of loose or missing teeth), bite problems, dry mouth, or any other dental concerns, the team at Robson Dentistry in East Lyme, CT can help you discover solutions which will make eating and digesting your meals pain-free once again. Your healthy smile—and your healthy body—will thank you!
