Chances are, everyone will have to deal with a tooth cavity at some point in their life. In fact, tooth cavities are one of the most common dental concerns we see. Advances in modern dentistry make it possible for dentists to treat tooth cavities more conservatively and with restorations that mimic natural teeth perfectly.
Dr. Stephen Hoard is a family dentist in New Bern, NC. We offer complete care for children as well as adults. Our main concern is preventing tooth decay. Dr. Hoard recommends that you visit the dentist at least every six months for routine examination and professional teeth cleaning.
What Causes Tooth Cavities?
Plaque is a sticky substance that builds up along teeth, between teeth and around the gums. Bacteria in plaque become activated by sugar and starch in the food we eat. The bacteria produces acid which erode tooth enamel and can lead to the formation of a tooth cavity.
Brushing twice a day and flossing once a day is essential to removing plaque and bacteria from the teeth and therefore preventing cavities. You can also prevent cavities by limiting snacking between meals, avoiding sodas and candy, and drinking plenty of water.
Tooth Cavity Symptoms
We use advanced diagnostic technology like digital x-rays to identify early signs of tooth decay. Some patients may experience other symptoms like:
- White spots on teeth
- Dark or dull teeth
- Toothache
- Sensitive teeth
- Holes in teeth
Tooth Cavity Treatment
Dr. Hoard can prevent tooth cavities with professional cleaning and sealants, which are plastic coverings that protect teeth. If you already have signs of tooth decay, Dr. Hoard may recommend the following treatment:
- Composite Dental Fillings: Composite dental fillings are placed in a single visit, used to treat minor tooth cavities.
- Porcelain Tooth Fillings: If the tooth decay is more extensive, Dr. Hoard may use a dental inlay or onlay to protect the tooth.
- Root Canal: When tooth decay progresses to the root of the tooth, it can cause extreme pain. A root canal procedure will eliminate infection from inside the tooth and restore the tooth using a dental crown to prevent future problems.

Frequently Asked Questions
Can you stop or reverse a cavity once it starts?
Yes, but only if you catch it super early. In the very beginning, a cavity is just a weak spot where minerals have been lost from the enamel. Your saliva, especially with help from fluoride, can sometimes redeposit those minerals and repair the spot. This is called remineralization.
However, once the enamel breaks and forms a real hole, it can’t grow back on its own. That’s why early checkups are so important.
How long can you leave a cavity untreated?
It’s best not to leave one untreated at all. A cavity is like a slow leak; it doesn’t get better, it only gets bigger and deeper. Over months, it can eat through the enamel into the softer dentin layer underneath.
Once it reaches there, you might start feeling sensitivity or pain. If it reaches the inner nerve, it can cause a serious toothache and require a bigger procedure, like a root canal.
Does a small cavity hurt?
Often, a small cavity doesn’t hurt at all. That’s the tricky part! The hard outer enamel doesn’t have nerves, so you can have a cavity forming and not feel a thing. Pain usually starts when the decay gets deeper and reaches the inner layers of the tooth, where the nerves live.
How many cavities is it normal to get in a lifetime?
Almost everyone gets a cavity at some point. Studies show that over 90% of adults have had at least one. The average person gets between three and four cavities in their lifetime.
Getting a cavity is very common and definitely not something to be embarrassed about. Take it as a sign to work with your dentist and improve your prevention game.
What’s the fastest way to get rid of a cavity?
A cavity can’t be “gotten rid of” at home once it’s formed. The only sure way to fix it is to see a dentist. They will gently remove the decayed part of the tooth and fill the clean space with a strong, tooth-colored material.
This filling stops the cavity from growing and restores the tooth’s shape and strength. The process is quick, comfortable, and protects your tooth for the long term.
Why do I get cavities even though I brush?
Brushing is crucial, but cavities can still happen. You might miss spots, especially along the gumline and in the deep grooves of back teeth. Flossing is also essential to clean between teeth where a brush can’t reach.
Your diet, how often you snack or drink sugary things, and the natural strength of your enamel also play roles. Your dentist can identify your specific risk factors.
If my tooth doesn’t hurt, is the cavity really that bad?
Yes, it can still be bad. As we mentioned, no pain doesn’t mean no problem. A painless cavity is still actively growing and weakening your tooth structure. Waiting for it to hurt usually means the treatment will be more complex, more expensive, and might involve saving a tooth that’s now in serious trouble. Treating it early is always simpler, cheaper, and more comfortable.
