1. Tooth Decay
- The most common toothache cause is a cavity
, and the pain is usually sharp and inter-mittent. Once decay goes through the enamel, an acid eats away at the enamel and goes toward the middle layer or dentin of the tooth. This creates a sensitivity to cold, hot, and often sweets.
2. Cracked or Broken Teeth
- Pressure from biting and chewing over years can weaken teeth. Biting down on hard objects (such as nuts, popcorn and hard candy) can cause a tooth or the filling or the root to crack and even break
. This aching pain can be felt in the tooth and the gum area of the tooth.
3. Inflammation of Tooth Pulp
- This is known as Pulpitus, where the nerve or center of the tooth has become inflamed. Pressure builds inside the tooth causing mild to extreme pain.
4. Sensitive Teeth or Receding Gums
- Sometimes a tooth or teeth, or receding gums, become sensitive to cold or hot temperatures. Even brushing with a toothbrush can produce this sensitivity. In this case, your dentist may recommend a soft or medium toothbrush. He may recommend a toothpaste, such as Sensodyne, or he may treat your teeth with fluoride.
- An abscess
is caused when an infection forms at the tip of the tooth root. The abscess is comprised of pus and causes inflammation of the tissues in the tooth resulting in throbbing, sharp pain. Common causes of abscesses are found in teeth that are untreated or that have advanced gum disease.
6. Gum Disease
- Periodontitis and Gingivitis are both caused by an infection of the gums
around the teeth. With the disease, Periodontitis, a gum abscess may occur on the outer tissue. With Gingivitis, the infection causes inflammation of the tissue. In either case, this infection can cause bone loss and deterioration of the gums.
7. Impacted Teeth
- When teeth grow too close together and are prevented from moving into their proper place in the mouth, they are impacted. This happens most often with wisdom teeth, and can create pain and jaw soreness. The jawbone is unable to accommodate the extra teeth which remain stuck under the gum.
8. Wisdom Teeth
- A toothache at the back of your teeth or mouth could be caused by impacted wisdom teeth or one wisdom tooth. In this case, your dentist will probably order an X-ray and could indicate the need for extraction of your wisdom teeth
9. TMJ or Misaligned Bites
- When a person's jaw or teeth are misaligned, it is called Malocclusion. This indicates that the force or pressure on the teeth is not distributed evenly. This can cause an inflammation in the nerve of the tooth or teeth..
TMJ (Temporomandibular Joint) and misaligned bites can cause clenching or grinding of teeth. Both grinding and clenching are detrimental, sometimes causing teeth to fracture, wear away the enamel surface of the tooth and often resulting in pain or toothache. Clenching and grinding aches can occur more during the night.
10. Sinus Cold or Infection
- The sinus cavity is just above the upper jaw. A sinus cold or sinus infection is often felt in your upper teeth, but has nothing to do with your teeth. A dull, aching pain may be felt--but once the sinus infection is gone, the toothache goes away as well with no damage to the tooth or teeth.
