That’s a good question! But first, we’re going to do that roundabout thing where we consider other questions before circling back to our original topic. Trust us, we’ll get there!

• Why Get Your Teeth Cleaned Professionally?

Before you consider how often to have your teeth cleaned, you might be wondering why you need to have them cleaned professionally at all. After all, you’re doing all the right things. You brush twice a day for two minutes each time. You floss at least once a day. You even use a soft-bristled brush to protect your enamel. Shouldn’t this be good enough?

Conscientious dental hygiene at home is a very good thing, but, when it comes to plaque and tartar, it might not be good enough. Plaque, especially between the teeth and along the gum line, is easy to miss. In a matter of days, that overlooked plaque hardens and becomes tartar. While you can do a lot to remove food particles and plaque at home, once plaque hardens into tartar, a professional cleaning is necessary to remove it safely.

• Why Worry About Plaque and Tartar You May Have Missed?

Because you want to avoid cavities and gum disease. You know that the bacteria in plaque cause tooth decay, but did you know that plaque and tartar can be a real problem for your gum health as well? Plaque and tartar irritate delicate gum tissue, causing inflammation and gingivitis (mild gum disease). If you have chronic bad breath, if your gums are swollen, red, or painful, if your gums bleed easily when you’re brushing and flossing, you might have gingivitis.

Left untreated, mild gum disease can become periodontitis, a more serious condition. Irritation and inflammation cause gum tissue to pull away from the teeth, forming deep periodontal pockets where bacteria and infection spread. Infection and inflammation response damage the bone and tissue supporting the teeth, and teeth become loose or lost altogether. In fact, periodontal disease is the leading cause of tooth loss in adults.

A professional cleaning at our San Jose is one of the preventive steps you can take to reduce your risk of gum disease.

• What Happens During a Cleaning?

First, your teeth and gums will be checked carefully to see if there are any problems that we need to address before the procedure begins.

The first step in cleaning usually involves removing plaque and tartar. This may be done with an ultrasonic scaler, a hand scaler, or a combination of both. Plaque and tartar need to be scraped from tooth enamel above and below the gum line to prevent cavities and gum disease, so this is definitely a job for a dental professional. Gum attachment around the teeth will be checked, and shallow pockets will be cleaned. Your dentist will have suggestions if you have deeper periodontal pockets caused by gum disease.

After all the plaque and tartar have been removed, your teeth will be polished with a gentle abrasive to remove surface stains. There are two common methods of polishing: applying a special gritty toothpaste with a small rotating cup, or air polishing, which uses a stream of fine abrasive powder, water, and pressurized air. (If you have your teeth cleaned more than twice a year, your dentist will let you know if polishing is advisable during every visit.)

Next, flossing. A professional flossing will remove any remaining plaque from between the teeth. This is a good time to double check your own flossing technique and ask for any tips which will make your personal flossing more effective.

Finally, after rinsing, a fluoride treatment might be applied to strengthen your enamel, and you’re good to go. The entire process usually takes between 30-60 minutes.

• So, How Often Should You Have Your Teeth Cleaned?

That is a good question, and we did get there! But we don’t have just one answer for you. As with every aspect of your dental care, Dr. Ashmita Shetty will recommend cleaning treatments and procedures with your specific dental needs in mind.

• If your teeth and gums are healthy, and you don’t have periodontal disease or risk factors for periodontal disease (such as smoking, a family history of gum disease, or medical conditions such as diabetes), you might be able to get by with two cleanings each year.
• If you have a history of periodontal disease, or are at higher risk for periodontal disease because of one or more risk factors, Dr. Ashmita Shetty might recommend more than two cleanings each year.

Professional cleanings play an important role in your preventive dental care. Whether it’s done once a year, twice annually, or more often as needed, a cleaning performed by a dental professional takes only a short amount of your time and provides you with long-term benefits—not only a brighter smile, but healthier teeth and gums!

“What is the strongest substance in the body?” If this question comes up on trivia night, be prepared to impress your team when you confidently answer, “Tooth enamel!”

Tooth enamel? The reason for this surprising answer lies in the biology of our teeth. Minerals make up well over 90% of our enamel, a much higher percentage than is found anywhere else in the body, including our bones. But unlike bone tissue, which can heal and regenerate, tooth enamel cannot. Even though it is extremely strong, enamel can be damaged by a process called demineralization.

Demineralization

Demineralization is a result of acids at work in our mouths. Acids actually break down the minerals in our enamel, making the enamel softer. Over time, bacteria attack deeper into the tooth, eventually leading to decay. Acidic foods like sodas, citrus, pickles, and coffee are obvious culprits in providing an acidic environment, but there are other problem foods as well. We all have bacteria in our mouths, which can be helpful or harmful. The bacteria in plaque use the sugars and starches we eat to produce even more acids.

This process is something that takes place very quickly. In fact, even brushing too soon after eating something acidic can damage the demineralized surface of a tooth. Waiting at least 20 to 30 minutes to brush gives our bodies a chance to restore the enamel surface in a process called remineralization.

Remineralization

Our bodies are actually designed to help protect our enamel, and the most important part of this process is saliva production. Saliva cleanses our teeth and reduces levels of acidity. And our saliva constantly washes important minerals over our teeth. Calcium and phosphate ions rebuild and strengthen molecules where demineralization has taken place. This process is called remineralization.

We have other ways to help the remineralization process along. Fluoride toothpastes and fluoridated water speed up the movement of mineral building blocks back to the surface of the tooth. Fluoride also strengthens our teeth so that they resist acids and demineralization better than teeth without fluoride, making them less vulnerable to cavities.

New products are available for home and professional use that are designed to increase remineralization—talk to Dr. Ashmita Shetty at our San Jose office if you would like the latest recommendations. In fact, talk to us about tooth-friendly menus, the best toothpastes, brushing techniques, and all the ways to keep your enamel its healthiest. You’ll be answering all those trivia questions with a strong, confident smile!

There are lots of ads out there for toothpastes that claim to repair damaged tooth enamel.

Can you treat cavities and tooth decay at home? Well, mostly, no, you can’t.

Can you strengthen your enamel at home? Very possibly—in some circumstances. Let us explain!

Cavities and tooth decay start forming when the enamel on the tooth’s surface breaks down. To discover what causes this breakdown, we need to see how chemistry works with our biology.

Tooth enamel is mainly made from calcium and phosphate ions. These minerals combine to form hydroxyapatite, crystals which make up around 95% of our enamel. Hydroxyapatite crystals are so strong that tooth enamel is the hardest part of our bodies. What can weaken a substance this strong?

Acids. Acidic foods and drinks, as well as acids created by the bacteria in plaque, strip away calcium and phosphate ions in enamel, weakening the surface of the tooth. This is a process called demineralization, and it’s the first stage of tooth decay. Left alone, weak spots will become bigger and deeper until they form cavities.

And tooth enamel, unlike the rest of your body, isn’t living tissue. It can’t regenerate. Once bacteria and acids have created a deep enough cavity, only Dr. Ashmita Shetty can repair it by removing decay and filling the tooth.

Wait, this sounds a lot more like “No, you can’t repair your enamel” and much less like “It’s possible to strengthen your enamel.” But we’re not through!

Demineralization doesn’t equal cavities—yet. Careful attention to your habits and your diet can make a difference in whether your enamel continues to weaken or becomes stronger.

Our body’s first defense against demineralization is saliva. Calcium and phosphate ions in saliva bathe the teeth throughout the day, restoring the minerals which have been lost. This is called remineralization. Saliva also helps neutralize acids from the foods we eat. But with a diet heavy in acids, or a lot of plaque buildup, saliva just can’t keep up with the damage.

That’s where “enamel-repair” toothpastes come in. Toothpastes are available that contain hydroxyapatite to restore calcium and phosphates to weakened enamel. But for many of the most common enamel-repair toothpastes, the not-so-secret secret to their effectiveness is fluoride.

Dentists recommend fluoride toothpastes for several very good reasons. Fluoride is attracted to the minerals in tooth enamel and bonds with them. Once bonded, fluoride attracts the calcium and phosphate ions in saliva, helping restore lost minerals to the enamel. Even better, when fluoride bonds with the calcium and phosphate in our enamel, fluorapatite is created. This is a crystal even stronger and more acid-resistant than hydroxyapatite.

If you’re concerned about the strength of your enamel, and especially if you notice any signs of acidic erosion, talk to our San Jose dental team right away. Dr. Ashmita Shetty can:

• Recommend over-the-counter toothpastes or professional fluoride applications to help reverse early demineralization
• Provide dental bonding, a crown, or a veneer to protect a tooth with serious erosion
• Treat a cavity caused by more advanced tooth decay.

Keeping your enamel healthy at home can take many forms. By careful brushing and flossing to remove plaque, by watching the acids in your diet, by making sure you’re properly hydrated, and by using fluoride toothpaste, you can both reduce the risk of demineralization and help restore weak spots in your tooth enamel.

So, can enamel-repair toothpastes effectively repair your teeth? Yes, they can be effective—if demineralization is in its early stages and if you make them a regular part of your daily dental routine.

Just like that, it’s almost summertime. As the spring season ends, perhaps these lighter, brighter days are inspiring you to do a bit of last-minute spring cleaning. Or perhaps they’re not. No judgment here!

What we can recommend wholeheartedly is finishing the season with a clean, sparkling smile. And we have some bright ideas for you!

Refresh Your Cleaning Technique

Tooth brushing can become so automatic that we don’t think about the basics anymore. And suddenly, we’ve finished brushing in half the time we used to, and, hey, how long has that floss been sitting on the counter, anyway? We suggest some mindful cleaning for a healthier smile.

• Spend two minutes brushing, at least twice each day.
• Make sure you reach all the surfaces of your teeth, inside, outside, and on top of your molars.
• Use short, gentle brush strokes, covering a tooth or two at a time.
• Angle your brush to clean along the gum line. Plaque around the gums leads to irritation and inflammation, and is a common cause of gum disease.
• Use vertical strokes to clean the inside of your front teeth.
• Floss at least once each day.

Good Cleaning Requires Good Tools

Since we’re tidying up, let’s talk about some helpful cleaning tools. Is your toothbrush looking a bit—long in the tooth?  

After three to four months of brushing, your toothbrush bristles start to break down. Frayed and matted bristles can’t clean as effectively as a toothbrush in top shape. Each change of season is a good time to remind yourself to change brushes.

And, while you’re shopping, remember:

• Soft bristles are almost always all any brusher needs. Even medium bristles can be abrasive to tooth enamel. And brush gently—scrubbing is also abrasive.
• If you use an electric toothbrush, those toothbrush heads need to be replaced, too! In fact, because these brushes often have shorter bristles, heads might need to be replaced every two to three months.
• Use fluoride toothpaste to clean and protect your teeth.
• Don’t forget the floss!

If you’re not a fan of your current floss, take another look at the dental aisle in your local store. There are lots of new flossing options out there just waiting to be sampled. If manual flossing is difficult, consider a water flosser. Dr. Ashmita Shetty can help you find just the right floss for your one-of-a-kind smile.

And speaking of your dental team . . .

Some Cleaning Jobs Require Professional Help

Dentists typically recommend a professional cleaning at our San Jose office twice a year to make sure you’re free from built up plaque and tartar. How does your dental team go about getting your teeth cleaner than you can get them at home? With special training and special tools.

• Plaque and tartar need to be removed from tooth enamel above and below the gum line to prevent cavities and gum disease, and tartar can only be removed by a dental professional. Your hygienist might use an ultrasonic scaler, a hand scaler, or both to gently scrape away sticky plaque and hard tartar.
• Teeth are polished with a gentle abrasive to remove surface stains. This can be done with a special toothpaste applied with a small rotating cup, or with an air polisher, which removes stains with a stream of fine abrasive powder, water, and pressurized air.
• An expert flossing will remove any remaining plaque from between the teeth.

Bonus: Your hygienist can point out spots you’ve been missing to help make your home brushing and flossing more effective.

Clean and Bright

Increasing daylight can brighten your mood—and so can a whiter smile! Over time, smiles get dimmer without our even noticing, thanks to tooth-staining foods and drinks, medications, smoking, or thinning enamel as we age. If you’re feeling self-conscious because your smile isn’t its sparkling best, consider a whitening treatment.

• Whitening Toothpastes

Whitening toothpastes use chemicals and mild abrasives to remove surface stains caused by foods, beverages, and smoking. If you’d like to give a whitening toothpaste a try, ask Dr. Ashmita Shetty for suggestions.

• Whitening Strips and Gel Trays

Whitening gels can be applied at home with strips or tray kits. These peroxide-based gels are stronger than the formulas used in toothpaste, but can be irritating. Talk to Dr. Ashmita Shetty to learn how to achieve the best and safest outcome with these products.

• Office Treatment

Whitening treatments at our San Jose office are generally faster, more effective, and last longer because this process uses a more powerful whitening agent. That’s why it should only be applied by a dental professional, who will examine and prepare your teeth, protect the surrounding gum tissue, and monitor your treatment throughout.

Spring’s coming to an end, but taking care of your dental health is always in season! A clean smile isn’t just a more confident smile, it’s a healthier one. Talk to your dentist for more tips to create your best and brightest smile at any time of year.
