Time for Some Spring Cleaning!

April 2nd, 2025

Just like that, it’s Spring, and the world looks brighter! The skies are sunnier. Daylight in Walnut Creek, California lasts longer. And your smile can be brighter, too—with a little bit of spring cleaning.

After all, sometimes dental habits become so automatic that we don’t pay them as much attention as we should. Without careful daily brushing and flossing, you could start to see surface staining on your enamel. Or red and swollen gums. Or tartar deposits along the gumline or behind your teeth. 

The start of the season is a good time to spring ahead with a plan for better oral health, and we have some simple ideas to help you clean and protect your smile all through the year.

Assemble the right tools.

  • Use a soft-bristled toothbrush, because anything firmer can be hard on your tooth enamel and gums. If you’re having trouble removing food particles and plaque, an electric toothbrush might be a game changer.
  • Find the right floss. If you’ve been neglecting flossing because it’s difficult, or if you have mobility issues, there are lots of options available to improve efficiency and comfort. Whether it’s floss picks, interproximal brushes, or water flossers, Dr. Cynthia Stephenson can recommend the best products for your individual needs.
  • Choose fluoride toothpaste. Fluoride not only helps prevent cavities by creating an unfavorable environment for cavity-causing bacteria, it also actually strengthens tooth enamel as well. Win/win!

Use those tools!

  • Brush all the surfaces of your teeth carefully and thoroughly (no need to scrub) and brush along the gumline at a 45˚ angle. This will help prevent plaque from accumulating above and below the gumline, where it can harden into tartar.
  • Brush often enough and long enough. The team at Cynthia Stephenson, DDS generally recommends brushing twice a day, for two minutes each time. 
  • If you wear aligners, a retainer, a mouthguard, a nightguard, or other appliances, brush your teeth before wearing them. You don’t want to trap food particles or bacteria in your appliance!
  • Floss at least once a day, or more often as recommended. Proper flossing can be difficult sometimes, so ask Dr. Cynthia Stephenson for the best techniques.

Make sure your dental products are in top shape.

  • Replace your toothbrush as often as necessary. After three months or so, bristles start to fray. They don’t clean as effectively, and they could be abrasive to gum tissue. Change out your brush every three to four months, including the head on your electric brush. A good way to remember is to change your brush with the change of seasons. 
  • Check the date(s)! Many toothpastes, mouthwashes, and other oral supplies come with a “best used by” date, ensuring that your products remain safe and effective.
  • Choose the right toothbrush holder. Your brush should air-dry upright, because germs thrive in closed, damp environments. And your holder shouldn’t allow your brush to touch other people’s brushes to avoid transfer of bacteria and viruses. Clean your brush holder regularly to remove toothpaste residue and germs.
  • Clean your aligners, retainer, mouthguard, night guard, and/or cases for your appliances as recommended. Bits of food, bacteria, viruses, and other germs collect there as well.

Work with the experts for your brightest smile.

  • See Dr. Cynthia Stephenson regularly. You’ll discover any problems which might be dimming your smile, and you’ll discover them early.
  • Schedule cleanings with your exams. The team at Cynthia Stephenson, DDS uses tools such as ultrasonic or hand scalers and polishers to remove stubborn plaque, tartar deposits, and surface stains that brushing can’t.
  • If you want brighter, whiter teeth, consider professional whitening. While whitening kits are available in almost any drug store or supermarket, office treatments or kits provided by Dr. Cynthia Stephenson use stronger ingredients and are more effective.

Easy steps, yes? Step up your cleaning routine, and you’ll have a springtime filled with not just brighter smiles, but healthier smiles, too!

Understanding Cavities

March 26th, 2025

Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Dr. Cynthia Stephenson will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Teeth, Bones—What’s the Difference?

March 19th, 2025

They’re often mentioned together, and that’s understandable. After all, they’re the strongest parts of the body, they’re made of many of the same elements, they both require a diet rich in vitamins and minerals to stay healthy, a pirate flag wouldn’t be the same without them–so, what makes teeth and bones different? Glad you asked!

It’s Elementary

Teeth and bones are so strong because of their mineral composition. They have the highest concentration of calcium and phosphorus in the body, and these minerals combine to create sturdy structures which support our bodies, protect our organs, and help break down and digest our food. And they work well together—healthy teeth maintain jawbone density, and healthy jaws hold our teeth firmly in place.

But there are important differences in the anatomy of teeth and bones as well. Bones contain living cells, blood vessels, and nerves. They grow larger as we grow. As we age, old bone tissue breaks down and is constantly replaced with new bone tissue. This process enables our bones to stay strong throughout our lives. And bones heal.

When you break a bone, your body begins working right away to protect and heal the damaged area. Blood cells help with clotting around the break. After a few days, collagen proteins work to replace the clotted cells and form a soft callus. Within weeks, calcium phosphate deposits strengthen the collagen framework. Over time, the bone hardens and reshapes.

And while tooth enamel is the hardest substance in our bodies—harder even than bone—it is not indestructible. Our enamel is basically composed of minerals rather than living tissue, so it can’t regenerate. The enamel covering our teeth doesn’t replace cells as they age, and it can’t create new tooth cells if a tooth is injured through damage or decay. This means that a cracked or broken tooth can’t knit itself together, and enamel lost to decay won’t grow back.

Dr. Cynthia Stephenson can restore your smile with fillings, or crowns, or even implants if necessary, but preventing injury to your teeth is always best.

Protecting Teeth and Bones

You can make sure your teeth and bones are their safest and strongest by being proactive.

External bone injuries can be avoided with the use of proper safety equipment. Helmets, padding, work boots—if your work or play recommends protective gear, use it! Fortunately, there’s also protective gear for teeth.

  • Helmets

Helmets not only protect against brain injury and concussion, they are often designed to protect the face, mouth, and jaw as well.

  • Mouthguards

Mouthguards protect the teeth, lips, tongue, and jaw from damages caused by physical contact and falls. They’re available over-the-counter, or ask Dr. Cynthia Stephenson to fabricate a custom guard for the most comfortable and secure fit. A custom guard is an excellent option for people with braces, bridgework, or other dental appliances.

  • Night Guards

Grinding and clenching the teeth at night can lead to loose and cracked teeth, headaches, jaw pain, and other unhappy consequences. Protect your teeth from the damage caused by bruxism (tooth grinding) by wearing a night guard.

Finally, one big difference between tooth and bone design: bones are safely hidden away inside the body, while our teeth are exposed to harmful plaque, bacteria, sugars, and acidic foods every day. Give your teeth the preventive care they deserve with twice-daily brushing, flossing, and regular visits to our Walnut Creek, California office. After all, your beautiful, healthy smile was never designed to be hidden!

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!
