Fluoride Treatments—They’re Not Just for Kids!

March 12th, 2025

Fluoride has been one of the great game-changers in children’s dental health. Drinking fluoridated water. Using fluoride toothpaste. Scheduling fluoride treatments. All of these child-friendly dental habits help prevent cavities and strengthen tooth enamel.

And we adults enjoy the benefits of fluoride as well. Drinking fluoridated water. Using fluoride toothpaste. If only we hadn’t outgrown fluoride treatments… or have we? Time to have an adult conversation about fluoride treatments!

  • To Start, Some Dental Chemistry

The enamel in our teeth is largely made of calcium and phosphate ions. These elements combine to form hydroxyapatite, the mineral crystals that make teeth and bones so hard and strong. But enamel isn’t indestructible. The oral bacteria in plaque create acids that cause demineralization, stripping away calcium and phosphate ions. This leaves the tooth surface weakened and vulnerable to decay.

Our bodies have a way of compensating for demineralization. Saliva is filled with calcium and phosphate ions that restore lost minerals. This balancing act goes on every day. When conditions in the mouth are too acidic, however, remineralization can’t take place as effectively. Here’s where fluoride is so beneficial.

  • Why Fluoride?

First, because fluoride helps remineralize. Fluoride works on the surface of the tooth to attract the calcium and phosphate ions in our saliva, restoring them to our teeth. Even better, it joins with these ions to create fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite. This means your teeth are not only remineralized, but stronger than they were originally!

  • Why Adult Fluoride Treatments?

While fluoridated water and fluoride toothpaste might be all you need for strong enamel, there are several conditions that make fluoride treatments a good addition to your preventive care at our Walnut Creek, California office.

  • Problems with dental hygiene. Consider fluoride treatment if you have trouble brushing and flossing, if you wear braces, or if there’s any other reason that makes daily cleaning more difficult.
  • Exposed roots. Gums often recede as we age, and can pull away from the teeth even further with added factors like gum disease, harsh brushing habits, teeth grinding, or smoking. As gums recede, parts of the tooth roots are exposed. Because roots are covered with cementum instead of the much harder enamel, they are more vulnerable to decay.
  • Dry mouth. Medical conditions, medications, and aging can cause a decrease in saliva production. Because saliva helps wash away food particles and bacteria, bathes the teeth with minerals that strengthen enamel, and neutralizes acids, less saliva can equal more cavities.
  • Our individual biology. Some of us are born with weaker tooth enamel, and so are more at risk for cavities—even with great brushing and flossing habits.

In all of these cases, fluoride treatments can provide the extra protection you might need for stronger tooth enamel and improved dental health.

  • Treatments Are an Easy Addition to Your Dental Appointment

Regular fluoride treatments are neither complicated nor time-consuming. Fluoride can be administered as a varnish, a gel, a rinse, or a foam. It can be applied with a brush, a swab, as a mouthwash, or in a tray. After application, Dr. Cynthia Stephenson will let you know if any follow up instructions, such as avoiding food and drink for 30 minutes after treatment, are necessary. That’s all there is to it. Protection lasts for months, and your dentist can let you know when a re-application is needed.

You’re doing the right thing by using a fluoride toothpaste and keeping up with your dental exams and cleanings. Ask Dr. Cynthia Stephenson if a fluoride treatment is something that could strengthen your teeth and help prevent decay—it could be a game-changer for your dental health!

Mouthguard Protection

March 5th, 2025

Let’s talk about mouthguards and night guards—two crucial appliances that protect your teeth and jaw.

We could talk about how important a mouthguard is when you lead an active life. Mouthguards protect teeth, delicate mouth tissue, and jaws from accidents and impacts.  

Or if you grind your teeth at night, waking up every morning with tooth or jaw pain, we can talk about how a night guard can be a quality-of-life-saver.

But we’re not going to talk about any of these important topics today. Instead of looking at how your mouthguard protects you, today we’re going to look at how you can protect your mouthguard.

If you want your guard to last longer, work better, and stay (and smell) cleaner, some basic tips make all the difference.

  • Keep your guard clean.

This can’t be stressed enough. Without a good cleaning routine, your guard can become discolored, develop an unpleasant odor, and even cause illness. Not very appealing, right? Happily, keeping mouthguards and night guards clean isn’t difficult.

When you wear your guard, whether during daytime activities or through the night, the same plaque that is present in your mouth makes itself at home in your appliance. And when your guard is in its case, that dark, moist environment makes it a perfect breeding ground for all kinds of bacteria, viruses, and fungi.

As soon as you take your guard out, rinse it off. Brush with a soft toothbrush to remove all the plaque, saliva, or food debris that might be lingering in your appliance. (If you are on the playing field, in the park, or at some other inconvenient location, rinse it and brush as soon as you can.) Toothpaste can help get your guard its cleanest, but can be too abrasive for some appliances.

Once you’ve cleaned it, let your guard air dry in a clean spot for about 30 minutes. Air drying helps prevent bacterial growth. After your guard has dried, return it to its case.

Once a week, you might need to give your guard a good soak in a mouthwash or other dental cleaning solution.

Since cleaning instructions can be different depending on which type of guard you have, be sure to follow our instructions if you have a custom guard, or follow the manufacturer’s cleaning instructions if you have a store guard.

  • Keep it safe.

When your guard isn’t in your mouth, it should be in its case. Lying loose on the bathroom counter or tumbling around in your gym bag puts your guard at risk for breakage and bacteria.

And don’t forget to clean your case thoroughly every few days and air dry it as well. Bacteria, viruses, fungi, mold, and other unwelcome guests can collect in your case, too.

  • Keep it only as long as it’s in good condition.

You can purchase mouthguards from sporting or drug stores, or Dr. Cynthia Stephenson can make you a mouthguard or night guard designed to fit your teeth perfectly. These appliances are made to be strong and durable, but they’re not indestructible. Over time they can wear down or become damaged, especially if you treat them carelessly.

Bacteria can lurk in dents and cracks, and you can cut your mouth on rough, sharp, or broken edges. But if your guard isn’t fitting properly, don’t resort to self-help! Trying to repair, reshape, or trim your appliance yourself is not a good idea, because it might affect its fit and protective ability.

Any sign that your guard isn’t fitting properly or shows signs of wear and tear could mean it’s time for a replacement. You can replace a store model, or ask our Walnut Creek, California team about repairing or replacing your custom guard. A mouthguard or night guard that doesn’t fit, doesn’t protect you.

Take care of your guard, and it will take care of you. The reward for the small amount of time and effort you put into caring for your mouthguard or night guard is a smile that will last you for a lifetime. That’s a benefit we can talk about all day!

Xerostomia: What does that mean anyway?

February 26th, 2025

Does your mouth always feel like it’s dry? If it does you may be suffering from xerostomia. Xerostomia is defined as dry mouth resulting from reduced or absent saliva flow. There are various medical conditions that can cause this type of dry mouth, which you can ask more questions next time you visit us at Cynthia Stephenson, DDS.

Xerostomia can factor into both minor and more serious health problems. It can affect the ability to eat and enjoy food and it can jeopardize one’s dental health. Some of the more common symptoms can include sore throat, burning sensation in the oral cavity or tongue, and difficulty swallowing.

One of the more serious problems associated with dry mouth is an increased risk of tooth decay. Decrease in saliva causes more plaque to form and there is less saliva to act as a buffer to the things we eat and drink. Less saliva also means more food debris is retained in the mouth. These things can lead to an increase in tooth decay.

So, what causes xerostomia?

There are several things that may cause xerostomia. Among the biggest culprits are prescription medications. Some examples are antihistamines, antidepressants, anti-hypertensives, anti-anxiety agents, anti-diarrheals, bronchodilators, and muscle relaxers.

Certain diseases can also cause dry mouth. The more common ones include rheumatoid arthritis, lupus, diabetes, hypertension, and thyroid disease. Xerostomia is also common in patients being treated for cancer. Head and neck radiation as well as certain chemotherapy drugs can cause severe dry mouth.

What should you do if you are experiencing dry mouth symptoms? First make sure to hydrate with plenty of water. If you are taking medications that cause xerostomia, make sure to drink water before taking the medication as well as a full glass of water with the medication. Be diligent with brushing and flossing and discuss your condition at your next appointment with Dr. Cynthia Stephenson. We can recommend specific products to help moisten the oral cavity and reduce your symptoms such as saliva substitutes, xylitol products, and certain toothpastes. Another option may be a prescription home fluoride treatment to help prevent new cavities. You may want to try gum or candies to stimulate saliva flow but make sure they are sugar free! Avoid food and beverages that dehydrate such as caffeine and alcohol.

Xerostomia is a common problem that is currently on the rise. Our team can help you to reduce any symptoms and improve your comfort while living with a dry mouth. Contact our Walnut Creek, California office today!

What are dental sealants and how do they work?

February 19th, 2025

A dental sealant is a liquid that is applied to the teeth. The sealant hardens and provides a protective coating that is designed to reduce cavities and create a smoother tooth surface. Dental sealants are clear or white; they do not take away from the appearance of teeth. You can think about this treatment as being similar to varnish that protects a wood floor.

Sealants are not the same as fluoride treatments. The application is similar, but sealants are a semi-permanent protective coating. Dr. Cynthia Stephenson and our staff recommend that sealant applications for children begin soon after molars erupt, first molars around the age of six, and second molars around the age of 12.

Simple Application

Having sealants applied is not uncomfortable at all. First, your child's teeth will be cleaned and dried. A gel is applied, which helps the sealant adhere to the tooth, and then is rinsed away. Your child's teeth are dried again and the sealant is applied. A few seconds of exposure to a light source may be used to cure the sealant and make it semi-permanent. Sealants should last for a long time, normally between five and ten years.

Sealant Benefits

The coating on the surface of your child's teeth reduces the amount of acid contact. Normal acids in foods that are consumed can eat away at the surface of teeth. Bacteria also react to plaque formation and create more acid in the mouth. These small pits or weakened areas are prone to caries or cavity formation. Preventing cavities is a much better choice than drilling and filling damaged teeth.

A sealant also helps to smooth the chewing surfaces of your childn't teeth. The smoother surface is not as likely to retain small particles of food and bacteria. Your child's mouth stays cleaner and food is not left behind to form acids. The protective application can also be used on other teeth that have a rough surface, to protect the grooves or pits from decay.

After the sealant is applied, your child still needs to take proper care of his or her teeth. Regular brushing and flossing is required. Dr. Cynthia Stephenson may recommend fluoride treatments to strengthen and protect your child's teeth further.

If you have any concerns about sealants, please discuss them with during your child's next appointment at Cynthia Stephenson, DDS. We want your little one's teeth to stay healthy for life.
