Common Reasons for a Tooth Breaking Off

Having a tooth break off can be a painful and frustrating experience. If you find yourself dealing with this issue, it’s important to understand the causes so you can take steps to prevent it from happening again in the future. Here are some of the most common reasons why teeth break:

1. Tooth Decay

Tooth decay, or cavities, can weaken the structure of your teeth and make them more prone to breaking. This occurs when the enamel, the outer layer of your teeth, becomes damaged due to bacteria breaking down the sugars and starches in your food. As the bacteria continue to erode the enamel, they can create a hole or cavity in your tooth, making it more susceptible to breakage.

2. Trauma

Physical trauma to the mouth, such as a blow to the face or grinding your teeth, can cause your teeth to break. This is especially true if the trauma is strong enough to crack the enamel, which is the strongest and most durable layer of your teeth.

3. Bruxism

Bruxism, or teeth grinding, is another common cause of tooth breakage. This habit often occurs during sleep, and it can put a great deal of pressure on your teeth, causing them to chip or break over time.

4. Weak Tooth Structure

Some people are born with weaker tooth structures, which makes them more prone to breaking. For example, people with naturally thin enamel are at a higher risk of having their teeth break, as the enamel is less able to protect the inner structures of the teeth.

5. Old Age

As we age, our teeth naturally become weaker and more brittle, making them more prone to breaking. This can be due to a variety of factors, including the loss of tooth structure, changes in the composition of the jawbone, and the general wear and tear that comes with age.

6. Eating Hard Foods

Eating hard foods, such as ice or hard candy, can cause your teeth to break. This is because the pressure of biting down on these foods can be too much for your teeth to handle, causing them to chip or break.

7. Dental Procedures

Dental procedures, such as fillings or crowns, can sometimes weaken the structure of a tooth, making it more susceptible to breakage. For example, a large filling or crown can put extra stress on a tooth, which can lead to breakage if not properly supported.

Preventing Tooth Breakage

To prevent your teeth from breaking, it’s important to take good care of your oral health. This includes:

  • Brushing your teeth twice a day with a fluoride toothpaste
  • Flossing daily to remove plaque and food particles from between your teeth
  • Visiting your dentist regularly for check-ups and cleanings
  • Avoiding hard foods and drinks, such as ice and soda
  • Wearing a mouthguard at night if you grind your teeth
  • Avoiding using your teeth as tools, such as using them to open packages or rip open bags
  • Treating tooth decay and gum disease promptly to prevent it from spreading and causing further damage

If you already have a broken tooth, it’s important to see your dentist as soon as possible. They can assess the damage and determine the best course of action, which may include filling the tooth, placing a crown, or even extracting the tooth if necessary.


Tooth breakage can be a painful and frustrating experience, but it is often preventable by taking good care of your oral health. If you’re experiencing tooth breakage, it’s important to see your dentist right away to determine the cause and receive the proper treatment. By following the preventive measures outlined above and visiting your dentist regularly, you can help keep your teeth strong and healthy for years to come.
