When Is a “Cavity” Not a Cavity?

October 16th, 2025

Is this a trick question? After all, you probably already know quite a lot about cavities:

  • It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
  • Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
  • These acids gradually weaken teeth by dissolving minerals which help make up our enamel (a process called demineralization).
  • Over time, a hole, or cavity, develops in the tooth surface.
  • Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Some cavities aren’t discovered until you visit our Granite Bay office, but sometimes there are clear signs that there’s a problem.

  • You have tooth pain or sensitivity.
  • Your tooth changes color in spots where the enamel has decayed.
  • You might even notice enamel loss when a cavity is large enough.

So, if you have any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids—we do it ourselves with our choice of food and drink. Acidic foods are one of the leading causes of tooth erosion.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, wine, fruit juices, flavored teas, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

The symptoms of tooth erosion and damaged enamel can be very similar to those caused by cavities:

  • You suffer tooth pain or sensitivity
  • Your teeth appear discolored, as the enamel thins to reveal the yellowish dentin underneath
  • You notice missing enamel—your teeth become rounded or have little pits known as cupping

You call Dr. Jerry Martin right away if you suspect a cavity. Be just as proactive if you suspect erosion. Even though your symptoms may not have been caused by plaque and bacteria, acidic erosion from your diet leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

  • Enjoy acidic foods sparingly, or as part of a meal. This helps your saliva pH stay in the neutral zone.
  • Balance acidic foods with low-acid choices to help neutralize acids and restore a normal pH balance. (A good reason to pair wine or fruits with cheese.)
  • Use a straw! This simple solution keeps erosive drinks from bathing your teeth in acids.
  • Drink water instead of an acidic beverage, or drink it afterward to rinse your mouth. The pH of pure water? A perfect, neutral 7.
  • And what about brushing right after eating or drinking something acidic? Ask Dr. Jerry Martin if you should rush for your brush. We may recommend waiting 30 minutes or so after an acidic treat to give teeth time to remineralize after acids weaken them. Otherwise, brushing might cause more wear and tear on your enamel.
  • Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing your medical needs.

There’s no trick to it—watching your diet, brushing and flossing as recommended, using a fluoride toothpaste, and visiting Jerry Martin, DDS for regular checkups will help prevent tooth erosion. We can restore eroded enamel with bonding, veneers, or crowns if the erosion is serious. Better still is to catch erosion before symptoms appear to keep your teeth their strongest for a lifetime of healthy, beautiful smiles.

Root Canal FAQs

September 24th, 2025

Most people hear the word root canal and panic. With today’s state of the art equipment and improved local anesthetic devices, and some knowledge, a root canal does not have to cause panic. Root canals are a common dental procedure, done quite often at our Granite Bay office.

Why do I need a root canal?

There are several reasons why Dr. Jerry Martin may suggest a root canal including:

  • An infection in your tooth that has reached the nerves
  • A deep cavity that cannot be filled because the pulp and nerves are also effected
  • Injury to the tooth
  • A deep cracked tooth
  • Broken tooth
  • Repeated fillings of the effective tooth

What is a root canal?

A root canal is a dental procedure that is used to prevent the loss of a tooth and relieve pain. Inside your teeth is pulp which consists of soft tissue blood, connective tissue, blood vessels, and nerves. When the pulp becomes infected, swollen or diseased a root canal is necessary to save your tooth. During a root canal, Dr. Jerry Martin will remove the infected pulp. The tooth’s root canals and pulp chamber of your tooth will be cleaned, so all the diseased pulp is removed and then your tooth will be sealed.

What to Expect During a Root Canal

Your root canal will start out just like any other dental procedure. We will go over any questions you may have, and then numb the area surrounding the tooth. After the area is numb the root canal will begin.

The amount of time it takes to do your root canal varies depending on number of roots that need to be cleaned. Most teeth have one root canal, while others have between two and four. For a single canal, the procedure usually lasts less than an hour. The more canals your tooth has the longer amount of time it will take and in some cases, you will require more than one visit.

How much pain will I have after a root canal?

Once the local anesthesia wears off, your pain can be controlled by over the counter pain medications such as Ibuprofen, Naproxen, or Acetaminophen. In some cases, Dr. Jerry Martin may prescribe a prescription dose of pain medication. Within two days you should be feeling much better and able to return to your regular lifestyle.

What is a crown?

September 17th, 2025

If you have never had a crown before, you might be wondering why crown treatment is best, what the procedure involves, and which type of crown to choose. Let’s get down to the basics of crowns!

A crown is the best way to treat many dental conditions, either to strengthen and save the tooth or to improve its appearance. We might suggest a crown if you have any of the following conditions:

  • A filling that needs to be replaced, without enough tooth structure left to fill properly
  • A tooth that is fractured or broken, or so weak that it might fracture
  • A recent root canal
  • An implant
  • A bridge which needs a crown to serve as the base for attachment
  • A tooth that is discolored or irregularly shaped

On your first visit to our Granite Bay office, Dr. Jerry Martin will prepare the tooth that will be receiving a crown. A tooth might have to be built up if there isn’t enough of the original tooth left, or the top and sides of the tooth will be shaped down so that the crown fits smoothly and evenly with your other teeth. An impression will be made and sent to a dental lab so that a crown with the perfect fit for your tooth and mouth can be created. A temporary crown will be put in place to protect your tooth while the final crown is fabricated.

 The permanent crown is a cap which covers your tooth. It can be made of various materials, which all offer different advantages:

  • Metal Crowns—made of gold, platinum or base metal alloys, these are the longest lasting. Because of their metallic color, they are often chosen for back molars where they are less visible.
  • Porcelain Over Metal—because the color of the porcelain is matched to your natural teeth, these crowns look very realistic. Porcelain is more fragile than metal, so there is the possibility that they won’t be as durable.
  • Resin—less expensive than other options, but these crowns are more fragile and do not wear as well.
  • All Porcelain/All Ceramic—the most realistic looking option, especially for front teeth, and also suitable for anyone with a metal allergy. They are, again, not as strong as metal crowns, and can be subject to damage.
  • Stainless Steel—often used for baby teeth or as a temporary crown for adult teeth.

We’ll discuss your options and help you decide on the best type of crown for you. When the crown is finished at the dental lab, you will have one more visit where the crown will be secured in place. We will make sure your bite is comfortable and the color and appearance of the crown are satisfactory. We will also give you instructions for the next few days following the procedure, and can make adjustments if needed.

A crown is a perfect example of form and function working together: a crown maintains the beauty of your smile and preserves the health of your tooth. If you need a crown, we will be happy to talk to you about your best options for a strong, long-lasting, and natural smile.

How much calcium does my child need?

September 10th, 2025

When you were a kid, your parents may have told you to drink milk to build strong bones and grow tall and strong. Now that you have children of your own, you may hear yourself parroting those instructions you received years ago. Getting enough dairy is essential for young children whose teeth are growing. A child who consumes the recommended daily serving of dairy will develop healthy, strong teeth for the rest of his or her life.

So, which foods are the best in terms of acquiring the right amount of calcium? Milk and other dairy products are excellent sources of calcium. Milk also contains vitamin D, phosphorus, magnesium, and proteins. Magnesium promotes calcium deposits in your enamel, while phosphorus forms a small but important barrier against acidic foods that cause cavities. Vitamin D and protein are used by a child’s body to build bone tissue and maintain dental health.

According to a recent study, the majority of Americans, including children, do not receive enough calcium. In fact, according to the Academy of General Dentistry, only one in five children meets even the minimum standards for calcium consumption. The U.S. Department of Agriculture recommends that children under the age of eight should receive two and a half cups of dairy per day. Children older than eight need three full cups, the same as adult men and women. In addition to milk, eating yogurt is a great way your child can increase his or her dairy consumption. Drinking sugary beverages in place of milk causes cavities and tooth decay.

If your child does not get enough dairy consumption, they run the risk of improper tooth development and other dental health problems. Dr. Jerry Martin and our team at Jerry Martin, DDS encourage you to monitor your child’s dairy consumption to ensure he or she grows healthy teeth to last a lifetime.
