Tooth pain without a visible cavity can be confusing. You feel the discomfort, but when you check your teeth, everything seems fine. Many patients across Mountain Ash, Tredegar, and Cardiff experience this kind of pain and often wonder what’s really causing it. The truth is, tooth pain without a cavity can have several other dental or gum-related causes. Here are the seven most common reasons and when you should visit your dentist.

1. Tooth Sensitivity
If you feel sharp pain when having hot, cold, or sweet foods, it could be tooth sensitivity. This happens when the outer layer of your teeth becomes weak, or your gums move back, exposing the sensitive part of the tooth.
Tip: Try using toothpaste designed for sensitive teeth and avoid extreme temperatures until you see your dentist in Mountain Ash, Tredegar, or Cardiff for an assessment.
2. Gum Recession
When gums start to recede, they expose the tooth’s root surface, causing pain even when there’s no decay. You might also notice bleeding while brushing or visible tooth roots.
Treatment: Visit your nearest dentist in Mountain Ash or Tredegar for a professional cleaning or gum treatment to protect your roots.
3. Cracked or Fractured Tooth
Even a small crack can irritate the inner pulp, causing discomfort when biting or chewing. These cracks are often too small to see but can cause a toothache without a visible cavity.
Solution: Your dentist in Cardiff or Mountain Ash can take an X-ray to check for fractures and recommend bonding, a crown, or a root canal if needed.
4. Grinding or Clenching (Bruxism)
If you wake up with sore teeth or jaw stiffness, you might be grinding your teeth at night. Constant clenching puts pressure on teeth and leads to dull, ongoing pain.
What helps: A custom-made nightguard from your dentist in Tredegar can prevent damage and relieve pressure on your jaw muscles.
5. Gum Infection or Abscess
A gum infection or abscess can mimic cavity pain. You may notice swelling, tenderness, or a small pimple on the gum.
Warning: Don’t ignore it; infections can spread quickly. If you’re in Mountain Ash or Cardiff, visit a dentist near you immediately to treat it before it worsens.
6. Sinus Pressure
If several upper teeth ache at the same time, the cause might not be your teeth; it could be sinus pressure. Since the roots of upper molars are close to the sinus cavity, inflammation from a cold or allergy can trigger pain.
Relief: Treating your sinus issue may help, but if pain continues, schedule a dental visit in Tredegar or Cardiff for a check-up.
7. Damaged Fillings or Old Restorations
Old fillings can become loose or cracked, leaving tiny gaps where bacteria or temperature changes irritate the nerve.
Fix: Your dentist in Mountain Ash can replace or repair old fillings to prevent further sensitivity and infection.
When to See a Dentist
Even if your tooth looks normal, persistent tooth pain should never be ignored. The cause might be deeper in your gums, nerves, or jaw. Only a professional examination can determine the cause.

Frequently Asked Questions
Tooth pain without a cavity can happen for several reasons like gum recession, tooth sensitivity, or even a small crack that’s hard to see. A dentist can identify the exact cause with an examination and X-rays.
