Cavities: Problem and Solution - A Complete Guide to Tooth Decay
Nov 10, 2025

Tooth cavities are one of the most common dental problems, but the good news is, they’re also one of the most preventable! At Coimbatore Dental Foundation, we help you protect your teeth from decay and restore your smile with safe and effective treatments.
Let’s understand what causes cavities, their symptoms, and the best solutions to fix them.
What Is a Tooth Cavity?
A cavity (also known as tooth decay) is a small hole that forms in your tooth due to bacterial activity. When you eat sugary or starchy foods, bacteria in your mouth produce acids that attack the enamel. Over time, this weakens the tooth and leads to cavities.
Common Causes of Cavities
Poor brushing and flossing habits
Excessive intake of sugary foods and drinks
Not visiting the dentist regularly
Dry mouth (less saliva means less protection)
Plaque buildup on the teeth
Early Signs and Symptoms
Cavities start small, and early detection is the key! Look out for:
Tooth sensitivity (especially to hot or cold)
Black or brown spots on the tooth surface
Mild pain while chewing
Visible holes in teeth
Bad breath or unpleasant taste
If you notice any of these, visit the Coimbatore Dental Foundation immediately. Early treatment can save your natural tooth.
Best Solutions for Cavities
1. Fluoride Treatment (For Early Cavities)
If the cavity is caught early, fluoride helps restore enamel and stop further decay. It’s a quick, painless procedure that strengthens your teeth naturally.
2. Dental Fillings
When the cavity has formed a small hole, the decayed portion is cleaned and filled with materials like composite resin or ceramic. At Coimbatore Dental Foundation, we use tooth-colored fillings for a natural look.
3. Dental Crowns
If the decay is large and the tooth is weakened, a dental crown (cap) is placed over it to restore strength and function.
4. Root Canal Treatment (RCT)
For deep cavities that reach the pulp (nerve area), a root canal is the best solution. It removes infection, relieves pain, and saves your natural tooth.
5. Tooth Extraction (Last Resort)
If the tooth is too damaged to be saved, extraction may be required followed by options like dental implants or bridges to restore your smile.
How to Prevent Cavities
Brush twice a day using fluoride toothpaste
Floss daily to remove food particles
Limit sugary snacks and soft drinks
Visit your dentist every 6 months for cleaning and checkups.
Drink plenty of water to maintain saliva flow
