It really doesn’t happen very often. But sometimes you bite into something that is much harder than you anticipated. Sometimes you grind your teeth without realizing the pressure you’re putting on them. Sometimes you have a cavity that has stealthily developed beneath an earlier filling. And the result is—sometimes you lose a filling.

What to do when this happens? If you’re at a loss for ideas, we have some suggestions.

• Don’t panic

Usually, a cracked, broken, or lost filling is not an emergency situation. That being said, it’s still important to . . .

• Call us immediately

Dr. Cynthia Stephenson will be able to give you the best advice as to how to take care of your tooth until you can make an appointment. And if your dental problem might be a dental emergency, we can make sure you are seen as soon as possible.

• Take care of your tooth

Keep your tooth and the area around it clean. Brush gently to keep food particles away from the newly exposed tooth surface. You can (carefully) rinse around the area with a bit of water or salt water as recommended.

Your lost filling might not inconvenience you at all. But if you feel sensitivity when the tooth is exposed to air, or when you eat hot or cold foods, or if you feel pain when you bite down, let us know. We can recommend some over the counter medications and pain relievers that can help.

If you’re experiencing severe pain, call us at once.

• Diet

This might not be the time for sticky caramels, frozen treats, or extra-hot beverages. Make yourself comfortable by avoiding chewing with your compromised tooth, and postponing foods that could trigger sensitivity.

• Make a dental appointment as soon as you can

Don’t put off treatment, even if the filling was a small one, and even if the tooth is causing you no discomfort.

There might be further damage or decay that should be treated. A tooth that required a large filling is often more fragile than an intact tooth, and might need to be fitted with a crown in order to protect it. A missing filling might reveal deep decay which has exposed the pulp of the tooth to infection or damage, and a root canal might be necessary. A seriously damaged tooth might require extraction. Delaying treatment could result in a more complex restoration.

See us as soon as you discover a problem with your filling, and we will make sure not only that your tooth is treated appropriately, but that the reason for the lost filling is discovered. While no filling lasts forever, if the cause of your lost filling is tooth grinding or decay, it’s important to be proactive to prevent further problems.

Losing a filling? It really doesn’t happen very often. But that’s not a lot of comfort if you do happen to lose or break a filling. If you’re at a loss for what to do next, contact our Walnut Creek, California office. You’ll find yourself smiling again in no time!

Act One: Those 20 adorable baby teeth which begin arriving when you’re about six months old and are probably gone by the time you’re twelve.

Act Two: The 32 (if you have all your wisdom teeth!) adult teeth which start showing up around the age of six, and need to last the rest of your lifetime. Unless there’s an . . .

Act Three: Where science has discovered a way to repair damaged teeth or create replacements for lost teeth that would look and function just like our original teeth.

Sounds like science fiction, doesn’t it?

In biological terms, of course, we’re not there yet. But teams of scientists around the world have been working toward just this goal—the ability to repair a tooth with its own biological material or even grow a new tooth when an adult tooth is seriously damaged or lost.

Because the pulp—the living tissue inside each tooth—contains dental stem cells, some researchers are studying whether these cells can be used to regenerate the living pulp inside a damaged tooth. Even more exciting, there’s research being done into the possibility of using these stem cells to rebuild an entire tooth—pulp, dentin, and hard enamel exterior. Because the supply of usable dental stem calls is quite small, and process of guiding these cells to create all the varied parts of the tooth is quite complex, this research is in its early stages.

In other studies, scientists have focused on tooth regeneration by studying the teeth of other species. Mice, for example, have front teeth with open roots. This allows these teeth to keep growing up as they wear down, because stem cells inside mouse gums are always working to create new tissue. Even though our teeth are not exactly comparable (no open roots in human teeth!), finding out just how this tissue regeneration works in mice and other animals might help find an answer for human tooth regeneration.

Right now, these scientific goals are just that—goals for a future day. But in the meantime, your quality of life doesn’t need to suffer when you lose an adult tooth. You can enjoy a third act right now with dental implants.

Cosmetic concerns aren’t the only reasons why you want your complete smile restored in the event of a lost tooth. A missing tooth can lead to many unpleasant consequences:

• Speaking and eating can become more difficult.
• Lack of stimulation from biting and chewing can cause the bone beneath the lost tooth to shrink.
• Other teeth can shift to fill the gap left behind, which can affect tooth, bite, and jaw alignment.
• Loss of teeth can lead to loss of confidence.

Unlike dentures or bridges, dental implants are designed to function just like your natural teeth.

The post, or base, of each implant fuses with the bone in your jaw, acting as a “root” for the implant. Once the post has fused with the bone around it, a crown designed to match your other teeth in shape and color is secured to the post. You can eat, speak, brush, floss, keep your bone healthy, and smile confidently just as you did before.

Will biological replacements be ready for your third act in the near future? Probably not. But that’s not to say this will never be possible! In the meantime, take care of your teeth with daily brushing and flossing, eat a dental-healthy diet, and visiting our Walnut Creek, California office as recommended.

You do your best to keep your teeth intact and in place—but if you lose one through trauma or decay, talk to Dr. Cynthia Stephenson about an implant. Because in any stage of life, the most important result is the happy ending a healthy and confident smile brings you!

Did you know there are as many types of dental fillings as there are flavors of ice cream? Okay, maybe that’s an exaggeration. Still, when you visit the dentist with a cavity, there are many filling options. Most of us just sit in the chair, open our mouths, and let the dentist work his or her magic. But have you ever stopped to consider what the dentist is filling and restoring your decayed or broken tooth with?

Five types of dental fillings

There are five basic kinds of dental filing material. The dentist decides which type to use based on the degree of the decay, the cost of the material, and the type of dental insurance you have.

1. Dental amalgam, or silver fillings, have been used to fill cavities for more than 150 years. Dental amalgam is the most common type of dental filling. It's strong, durable, and less expensive than other types.
2. Composite fillings, or white fillings, are popular because the color matches the rest of your teeth. Composite fillings are a combination of resin and plastic. They are more aesthetically pleasing than silver fillings, but are also less durable.
3. Ceramic fillings are durable and visually appealing (tooth-colored), but they are expensive. They are made of porcelain and have been shown to be resistant to staining.
4. Glass ionomers are typically used on children whose teeth are still changing. Constructed from glass and acrylic, glass ionomers are designed to last fewer than five years. The benefit of these dental fillings is that they release fluoride, which protects the changing tooth from further decay.
5. Unless you’re a rock or movie star, gold fillings aren’t common. While a gold filling is durable, non-corrosive, and can last more than 15 years, it not only takes more than one dental visit to place, but, as you can imagine, it is expensive.

Our teeth are a lot more complicated than they look. Beneath that shiny white surface is an entire system of different cell tissues working together to keep each tooth vital and healthy.

• Enamel, the protective exterior of the crown (the visible part of the tooth), is the strongest substance in the body and the first line of defense against damage to our teeth.
• Dentin, the hard tissue under the enamel and cementum, has microscopic tubules that connect to the pulp.
• Pulp, the tissue at the center of the tooth, contains the nerves, blood vessels, and connective tissue that keep the tooth alive.
• Cementum, composed of connective tissue which forms the protective exterior of the root, also attaches to fibers in the periodontal ligaments which hold the teeth securely in the jaw.

Because cementum is below the gum line, it’s generally safe from the cavity-causing conditions that our enamel is exposed to every day. But there are still potential hazards that we should be aware of.

• Cementum Erosion

With a name like “cementum,” it’s logical to assume that this is the hardest tissue in the body. Actually, however, that distinction goes to our enamel. And if even our enamel can be damaged by bacteria and plaque, cementum doesn’t stand a chance!

How does cementum come in contact with cavity-causing bacteria? Gums often recede as a natural part of the aging process, leaving part of the root exposed. Gum disease, failure to brush and floss regularly, and heavy-handed brushing can lead to early gum recession. The newly exposed cementum is now exposed to the same conditions, which cause cavities in our enamel. But a root cavity can be trickier to treat and, because the cementum is not as strong as enamel, can progress more quickly. And if a cavity reaches the pulp, a root canal could be necessary.

But the erosion of cementum doesn’t have to result in a cavity to cause discomfort. When cementum is removed, the dentin beneath is exposed. Dentin, you’ll recall, contains tiny tubes that connect to the pulp of the tooth. The result? Conditions such as heat, cold, even an intake of air can cause tooth sensitivity as they stimulate the nerves in the pulp. If your hot coffee or ice cream cone is suddenly causing you pain, let us know. There are treatments, which can reduce tooth sensitivity.

• Gum Disease (Periodontitis)

In more severe cases of gum disease, the gums pull away from the teeth leaving pockets, which harbor plaque and bacteria. Left untreated, these pockets can become home to infections, which attack and destroy bone structure and connective tissue. Caught early, a treatment called tooth scaling and planing can help. In this type of deep cleaning, your dentist or endodontist will remove plaque and tartar and then smooth the root surface to make it harder for bacteria and plaque to stick. If the gums have receded too far, a gum graft might be necessary to protect the exposed roots.

• Trauma

The same traumas that can damage teeth above the gum line can result in injuries below it. Chewing on hard objects (ice, hard candies, wooden pencils), bruxism (tooth grinding), and sports injuries or accidents can cause cracks in the cementum. If your root is split or fractured, it might be possible to save your tooth, but sometimes extraction is the best option.

So how do you protect your cementum, hidden as it is under your gum line? The same way you protect the more visible parts of your teeth!

• Keep to a healthy daily routine of brushing and flossing. This will help prevent gum disease and keep gum recession at bay. Using a soft brush and brushing firmly but gently will remove plaque while protecting both enamel and cementum. If you notice tooth sensitivity, give us a call!
• Come in to our Walnut Creek, California office for regular dental exams. The best treatment for gum disease is prevention. When you come in for regular checkups, we are able to discover early signs of gum disease before it becomes a serious problem. If you are suffering from more advanced periodontitis, there are treatments available.
• Safety first when it comes to your smile. If you chew on hard objects, talk to Dr. Cynthia Stephenson about how to break the habit. If you grind your teeth, see us for solutions. If you play sports, let us know—often a mouthguard can help protect your teeth from injuries that could otherwise lead to more complex procedures or even tooth loss.

Maintaining your healthy dental habits is a lot like cementum—the foundation of a beautiful smile. Nothing complicated about that!
