Posted on 6/1/2026 by Duggan Endodontics Office
Have you ever experienced a throbbing pain in your tooth that just won't quit? It could be a sign of a diseased or decaying tooth, also known as a rotten tooth. This condition can cause significant discomfort and even lead to serious complications if left untreated.
What Causes Diseased or Decaying Teeth?
The most common cause of diseased or decaying teeth is dental caries, also known as cavities. Cavities are caused by a buildup of plaque and bacteria on your teeth. This plaque can erode the enamel, the hard outer layer of your teeth, and eventually reach the inner pulp, which contains nerves and blood vessels. When the pulp becomes infected, it can cause inflammation and pain.
Other factors that can contribute to diseased or decaying teeth include:
•
Poor oral hygiene: Brushing and flossing regularly are essential for removing plaque and bacteria from your teeth.
•
Sugary and acidic foods and drinks: These foods and drinks can contribute to the formation of plaque and erode tooth enamel.
•
Dry mouth: Dry mouth can make it difficult to remove plaque and bacteria from your teeth.
•
Certain medical conditions: Some medical conditions, such as diabetes, can increase your risk of developing dental caries.
Symptoms of Diseased or Decaying Teeth
The most common symptom of a diseased or decaying tooth is a throbbing pain that may be constant or come and go. Other symptoms may include:
•
Sensitivity to hot or cold: The pain may be worse when you eat or drink something hot or cold.
•
Swelling in the gums: The gums around the affected tooth may be swollen and red.
•
Pus discharge: You may notice pus discharge from the tooth.
•
Difficulty chewing: It may be difficult to chew on the affected side of your mouth.
•
Bad breath: A rotten tooth can cause bad breath.
What to Do if You Have a Diseased or Decaying Tooth
If you think you have a diseased or decaying tooth, it's important to see a dentist as soon as possible. The dentist will examine your tooth and take X-rays to determine the extent of the damage. Depending on the severity of the condition, the dentist may recommend one of the following treatments:
•
Filling: If the cavity is small, the dentist may be able to fill it with a composite resin or amalgam filling.
•
Crown: If the cavity is large, the dentist may need to place a crown over the tooth to protect it.
•
Root canal: If the pulp of the tooth has become infected, the dentist may need to perform a root canal. This involves removing the infected pulp and filling the root canal with a special material.
•
Extraction: If the tooth is severely damaged or infected, the dentist may need to extract it.
How to Prevent Diseased or Decaying Teeth
The best way to prevent diseased or decaying teeth is to practice good oral hygiene. This includes:
•
Brushing your teeth twice a day with fluoride toothpaste.
•
Flossing once a day.
•
Eating a healthy diet that is low in sugar and acid.
•
Seeing your dentist for regular checkups and cleanings.
Conclusion
Diseased or decaying teeth can be a serious problem, but they can be prevented with good oral hygiene. If you experience any symptoms of a diseased or decaying tooth, be sure to see a dentist right away.
