Why Does Your Tooth Hurt When You Bite Down but Feel Fine Otherwise?

A tooth that hurts when you bite down, then feels fine a moment later, could have a small crack, a loose filling or irritation around the root. Chewing puts pressure on the affected area, which can trigger a sharp pain that disappears once you stop. It's easy to dismiss, especially when you can eat normally on the other side. But if it keeps happening, there's usually a reason worth checking.

Could There Be a Crack You Can't See?

A cracked tooth doesn't always look broken. Sometimes the crack is so fine that you won't notice anything unusual in the mirror.

When you bite into something firm, the crack may open slightly and irritate the tissue inside the tooth. The pain can be surprisingly sharp, even if it only lasts a second.

Back teeth are particularly vulnerable because they handle most of the chewing pressure.

If you've noticed the same tooth hurting repeatedly, a dentist in Drummoyne appointment can help identify the cause.

That Old Filling Might Be Involved

Remember that filling you had done years ago? It could be worth having another look at it.

Fillings can wear down or loosen over time. Occasionally, decay develops around their edges, leaving the tooth more sensitive to pressure.

There are other possibilities too:

• A filling that's sitting too high: This can happen after recent dental work, making one tooth take more pressure than the others.
• Decay beneath a filling: The tooth may have weakened without any obvious damage on the surface.
• Teeth grinding: Clenching your jaw during sleep can leave the tissues around a tooth tender.
• Inflammation near the root: This can make chewing uncomfortable, even without a constant toothache.

One useful clue is when the pain started. If it appeared shortly after getting a filling, mention that when booking your appointment.

Does the Type of Pain Tell You Anything?

It can give your dentist a starting point. Different problems sometimes produce similar symptoms, though, so the pain alone won't tell you exactly what's wrong.

A dentist may need to examine the tooth, test how it responds to pressure or take an X-ray.

When Is It Time to Call a Dentist?

If the pain keeps coming back, book an appointment rather than waiting for it to become unbearable.

Swelling, fever or a persistent bad taste can suggest infection and should be assessed promptly.

For sudden or worsening symptoms, an emergency dentist in Drummoyne provider may be able to arrange urgent care.

Severe facial swelling or difficulty swallowing or breathing requires immediate emergency medical attention.

What Can You Do in the Meantime?

Until your appointment, give the sore tooth a break.

A few things may help:

• Chew on the opposite side of your mouth.
• Choose softer meals for a few days.
• Avoid chewing ice, hard lollies or nuts.
• Keep brushing gently and maintain your usual oral hygiene.

Try not to keep testing the tooth by biting down on something hard. It's tempting, but repeated pressure could make an existing crack worse.

What Will the Dentist Look For?

During a Drummoyne dental examination, the dentist will usually check for cracks, worn fillings and signs of decay. They may also check whether your teeth meet evenly when you bite.

Sometimes the solution is as straightforward as adjusting a filling. Other cases need a crown, root canal treatment or a different approach, depending on the damage.

If a particular tooth keeps hurting whenever you chew, make a note of where the pain occurs and what seems to trigger it. Those small details can help your dentist work out what's going on.
