Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?

The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.

The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.

Dental Fillings Come of Age

Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.

The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.

Dr. Ashmita Shetty can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our San Jose office so we can take the proper action to protect the health of your mouth.

It’s estimated that about one in every five people is affected by tinnitus, which is a ringing or noise in the ears. But tinnitus isn’t a condition in itself; it’s actually the symptom of an underlying condition. Some of these underlying conditions could be hearing loss, injury to the ear, or some sort of circulatory disorder.

Another common cause if tinnitus is a dental injury or dental issue, whether it involves the jaw or the temporomandibular joint, better known as the TMJ. “Somatic tinnitus” is the term given to the version that is attributable to injuries to the head or neck area. Symptoms of somatic tinnitus may include noticeable fluctuations in sound volume, intermittency, headaches, memory loss or increased forgetfulness, and an increased likelihood of being depressed or sad.

Dr. Ashmita Shetty will tell you tinnitus usually isn’t serious and is more common in older populations. For that reason, many people won’t even seek an answer to what’s causing it. But people can also experience more severe cases of tinnitus that can affect a person’s ability to complete everyday activities, which has a larger impact on their lives. For people facing these more severe cases of tinnitus, treatment may be necessary to increase their quality of life. It’s also worth noting that tinnitus seems to worsen with age, so while symptoms might not be a problem one year, they may be more significant and distracting the next.

If you have tinnitus that is caused by the misalignment of the TMJ or an injury to the mouth, that’s a condition that can be corrected by Dr. Ashmita Shetty and our team at Berryessa Dental Spa. We will work to relieve your symptoms by realigning the jaw or adjusting your bite with routine dental care. Sometimes we won’t even have to go this far, because an oral infection or gum infection may be causing your problem. We might also recommend other life changes, such as dietary adjustments and medication.

If you're experiencing tinnitus-like symptoms and have ruled out various other reasons for it, contact our San Jose office today. Dr. Ashmita Shetty and our team will carefully analyze your situation and put you on a treatment course so that you can kick the symptoms for good.

What to do to prevent gum disease? If left untreated, gum disease can lead to discomfort, infection, and even tooth loss. Bacteria in our mouths form a film called plaque. Plaque sticks to our teeth and can lead to gum inflammation. This inflammation can cause our gums to pull away from the teeth creating “pockets” which are home to infection and result in tooth and bone loss. Since the early stages of gum disease are often invisible, what is the secret to keeping our gums healthy?

Luckily, there is no secret to it at all! Preventing most gum disease is a simply a matter of following well-known guidelines, at home and in our San Jose office.

 Healthy Habits at Home

• Regular brushing and flossing

At least two minutes of careful brushing twice a day will help reduce bacteria and plaque. Use floss, picks, and other interdental tools to remove plaque from tight areas between the teeth that your brush might miss.

• If you smoke, now is the time to quit!

Smoking weakens your immune system, making it harder to fight infections and to heal. If you need another reason to quit, improving your oral health is a great one. Talk to us about ways to stop.

• Eating well

We all know sugar is no friend to dental health, and encourages bacterial growth. But eating apples, carrots and other crunchy vegetables can help remove food particles and stimulate the production of saliva, which fights bacteria production. Vitamins and minerals help strengthen bones and build healthy gum tissue. And a balanced diet supports not just your oral health, but the health and well-being of your entire body. Ask us for suggestions for a dental-healthy diet.

Regular Checkups and Cleanings

• We recommend a visit to our San Jose office every six months for a checkup. Dr. Ashmita Shetty can discover and treat gingivitis (early periodontal disease) and recommend a periodontal exam if there are signs of more severe gum disease. There are some individuals who develop gum disease even with great brushing and flossing habits, so it’s important to have a dentist’s evaluation.
• Having your teeth cleaned every six months will remove plaque that brushing alone can’t handle. If there are signs of more serious gum disease, a periodontal cleaning will remove plaque and tartar from both above and below the gumline.

Brushing, flossing, avoiding smoking, eating well, seeing Dr. Ashmita Shetty regularly—there’s no secret here! Talk to us about what you can do and what we can do to keep your gums healthy for a lifetime of beautiful smiles.

On a sizzling hot day, there’s not much that makes us happier than heading to the water for a quick swim, some gentle laps, or even a rousing game of water polo. And this being a sizzling hot dental blog, we are happy to offer some tips on how to make your summer swim good for your dental health as well as your mental health!

• Mouthguards

You might use your mouthguard all the time—for biking, or basketball, or skiing. But in the pool? Absolutely! Anyone who has played water polo knows what a physical workout it is. Elbows! Hard tosses! Collisions! And it’s not just pool sports. Water-skiing on the lake, surfing in the ocean—anywhere humans and solid objects are involved, tooth and jaw injuries are possible. Don’t spend valuable summer hours tending to a cracked or broken tooth as a result of sports accidents.

And, unlikely though it seems, even hanging by the pool can be hazardous to your smile. Hard concrete edges wait to greet surfacing divers. Slippery cement and tiles surrounding the pool are the downfall of many a swimmer running to jump back into the water. Be aware of possible dental dangers, and use a mouthguard as a great proactive way to avoid them.

• Swimming Pools & Chlorine

Ah, the smell of chlorine! We all want to know that swimming pools are as clean as they can be, and one method of keeping them that way is with the addition of antimicrobials to the water. But too much exposure to chemicals can cause enamel erosion, or even a condition called “swimmer’s calculus.” Swimmer’s calculus is recognized by a hard, brownish, tartar deposit that appears on the front teeth of swimmers who spent a lot of hours in the pool. It’s a cosmetic problem, but one that’s difficult to get rid of without a professional cleaning. If you’re a competitive swimmer, or simply someone who spends many hours a week in treated water, give us a call if you notice hard-to-remove discoloration or tooth sensitivity.

• Retainers

Different people have different opinions on whether or not your retainer should be exposed to the chlorine in pool water. (Or the salt in saltwater or the bacteria in lake water.) Ask us for ours! But you’re best off leaving it in your bag or locker, anyway, because retainers can be easily lost in the water. They might be able to survive a swimming pool, but a lake or ocean rescue is very unlikely. Just remember to put your retainer in a case, in a safe spot, and replace it when you’re out of the water for the day.

Enjoy your time on the water, and don’t forget to schedule an exam with Dr. Ashmita Shetty and a professional cleaning if you haven’t been in the office for a while. If you do have a dental problem or an accident, give our San Jose office a call immediately. We want to make sure you dive in to summer fun with a healthy, beautiful smile!
