If a decayed or damaged tooth is filled improperly or if an individual happens to be allergic to the metal amalgam used to make the filling, tooth pain may follow a dental restoration. Besides these, other common causes of dental pain after a filling may include the following.
- Trauma: When a dental restoration is performed, the sensitive pulp inside the tooth may be affected by shock; this is sometimes a cause of severe pain in the tooth after a cavity filling. Dental pain following restoration may be a sign that the tissues inside the tooth are not in the degree of health that was initially assumed before the filling was performed. Should this type of tooth pain persist, root canal work may be indicated.
- Referred Pain: The nerves in teeth nearby the one that has been repaired may pick up signals from nerves inside the tooth that’s been filled. This referred pain can be the cause of discomfort after getting a cavity repaired. This kind of pain can affect healthy teeth, even if they were uninvolved in the dental restoration process; severe pain can result.
- Misshapen Cavity Fillings: Dental restoration work needs to be smooth and flush with the tooth so as not to disrupt the usual movement and friction of the jaws and teeth. Occasionally, fillings may not be smoothed and polished sufficiently, resulting in irritation of the tooth cavity. If this occurs, the profile of the filling should be kept only once any swelling in the tissues around the cavity has subsided.
- Following Root Canal: A root canal treatment involves the removal of some of the soft tissue around the affected tooth, with some tissues being pushed downwards toward the base of the tooth. This process inevitably causes pain that persists after the root canal is completed. It goes without saying that the dentist can’t be held responsible for this kind of dental pain —it is an unavoidable consequence of even the best root canal work.
Those seeking relief of dental pain have a variety of options. The foremost is naturally a return trip to the dentist who performed the original work to discuss the problem, especially if the toothache is still present more than 14 days or so after the cavity was filled. A dentist can offer pain relief, often advising the patient on the best over the counter analgesics or prescribing stronger pain management in serious cases.
Household remedies for the pain of a toothache can be effective, as can other methods including aromatherapy and acupressure. Toothpastes containing desensitizing ingredients are also available; these may also be very soothing. To avoid unnecessarily prolonging the pain, it’s important to visit the dentist for routine follow-ups after the work is done.
