No, you absolutely cannot brush away a cavity. A cavity, or dental caries, is a hole in the tooth caused by the demineralization of tooth enamel due to acid produced by bacteria feeding on sugars. This is a physical deterioration of the tooth structure itself. A toothbrush, even with vigorous brushing, simply cannot repair this damage.
Here's what you need to understand:
What Causes Cavities?
Cavities develop over time through a process involving:
- Bacteria: Bacteria in your mouth feed on sugars and starches from food and drinks.
- Acid Production: As bacteria consume these substances, they produce acids.
- Enamel Demineralization: These acids attack the enamel, the hard outer layer of your teeth. This weakens and eventually dissolves the enamel, creating a cavity.
- Dentin Decay: If left untreated, the cavity will progress into the dentin, the softer layer beneath the enamel, and eventually to the pulp (the innermost part of the tooth containing nerves and blood vessels).
Can Brushing Prevent Cavities?
While brushing cannot remove a cavity, it is absolutely crucial in preventing them. Brushing removes food particles and plaque, reducing the amount of bacteria in your mouth and therefore minimizing acid production. This is your first line of defense against cavities.
What to Do If You Think You Have a Cavity
If you suspect you have a cavity, it is essential to see a dentist as soon as possible. Only a dentist can properly diagnose and treat a cavity. They may recommend:
Dental Fillings: This is the most common treatment for cavities. The dentist will remove the decayed portion of the tooth and fill the cavity with a material like composite resin, porcelain, or amalgam.
Dental Crowns: For larger cavities or severely damaged teeth, a crown may be necessary to protect and restore the tooth.
Root Canal: If the cavity reaches the pulp, a root canal may be needed to remove the infected pulp and save the tooth.
Tooth Extraction: In severe cases, extraction might be the only option.
What Happens If You Don't Treat a Cavity?
Ignoring a cavity can lead to several serious problems, including:
- Severe Tooth Pain: As the decay progresses, it can cause significant pain and discomfort.
- Abscess Formation: Infection can spread, leading to an abscess (a pocket of pus) at the root of the tooth.
- Bone Loss: Untreated cavities can damage the bone surrounding the tooth.
- Tooth Loss: Ultimately, a severely decayed tooth may need to be extracted.
Other Frequently Asked Questions
How often should I brush my teeth?
You should brush your teeth at least twice a day, for two minutes each time, using fluoride toothpaste.
What other measures can I take to prevent cavities?
Besides brushing, flossing daily, using fluoride mouthwash, and regular dental checkups and cleanings are vital in preventing cavities. A healthy diet low in sugary and starchy foods also plays a critical role.
In summary, brushing is essential for maintaining good oral hygiene and preventing cavities, but it cannot fix an existing cavity. Professional dental care is the only effective way to treat a cavity. Schedule an appointment with your dentist if you have any concerns.
