I have a toothache that’s been getting worse. Two days ago, my dentist looked at my X-ray from three months ago when I had a routine exam and cleaning. She said the X-ray looks fine, and my filling in the tooth is in good condition. She prescribed antibiotics in case I have an infection. How long should I wait before returning to her if the toothache doesn’t go away? Thanks, Rebekah from CT
Rebekah,
Although you had radiographs two months ago, your symptoms have changed since then. At that time, you didn’t have a toothache, so now, you need a new X-ray.
The previous images were likely bitewings, which only show the crowns of the teeth, not the roots. When diagnosing a toothache, a dentist should take a periapical X-ray that includes the tip of the root to see signs of infection in the pulp or surrounding bone.
Why Isn’t a Filling Check Enough If You Have a Toothache?
If your dentist only looked to see whether your filling was cracked, that’s concerning. A dentist must check for other clinical signs when you report pain.
These simple in-office tests can offer valuable insight:
- Tapping on the tooth to assess sensitivity in the ligament
- Response to cold—whether it worsens or alleviates the pain
- Sensitivity to heat, which may suggest nerve inflammation
- Pulp vitality tests, such as an electric pulp test to evaluate nerve health
If none of these were done, your dentist’s evaluation was incomplete.
Why Aren’t Antibiotics a Cure for a Toothache?
Prescribing antibiotics and telling you not to return if the pain subsides is the wrong approach. If the antibiotics relieve the pain, that confirms there’s an infection that needs further treatment — root canal treatment.
Antibiotics cannot eliminate the infection inside the tooth. They only reduce the surrounding inflammation in the bone. Once you stop taking them, the infection will return, often more aggressively.
When It’s Time for a Second Opinion Dentist
If the account you’ve given is accurate, this dentist did not take your symptoms seriously enough. You need a provider who will investigate thoroughly and treat appropriately. We recommend getting a second opinion.
