I had two fillings about ten years ago. One fell out, but that tooth doesn’t hurt. The other filling is still in place, but the tooth causes severe pain most of the time. Biting down doesn’t hurt, and only cold water helps, but the relief lasts just a few seconds. What could be causing this? – Thanks. Justino
Justino,
Your symptoms suggest that the pulp inside your painful tooth may be severely inflamed or dying. You may need root canal treatment to save the tooth. We would also recommend having a dentist examine the tooth that lost its filling before further decay develops.
Why Does Cold Water Temporarily Relieve Your Toothache?
Persistent pain that improves briefly with cold water, or pain triggered by heat, can indicate advanced pulp inflammation or damage that requires prompt treatment. Cold water may briefly relieve your pain by reducing inflammation or pressure inside the tooth. However, this type of pain can indicate a serious problem with the pulp, which contains the tooth’s nerves and blood vessels.
Decay may have developed beneath your existing filling and reached the pulp. As the pulp becomes inflamed or infected, pressure can build inside the tooth and cause severe pain, even when biting doesn’t hurt.

Root canal treatment
In some cases, the pulp begins to die, a condition called pulp necrosis. Older dental explanations describe gas buildup in dying pulp tissue as a cause of pain that improves with cold water. However, this symptom alone cannot confirm pulp necrosis.
Will You Need a Root Canal?
You may need root canal treatment if the pulp has become irreversibly inflamed or infected. A dentist can examine the tooth and perform tests to determine whether the pulp can recover. If root canal treatment is necessary, the dentist will remove the damaged or infected pulp, clean the root canals, and seal them to prevent further infection.
Sometimes, opening the tooth during emergency treatment can relieve pressure and pain. However, this is only part of the treatment, and the dentist must complete the root canal to protect the tooth.
We recommend scheduling a dental appointment as soon as possible.
