How long does the numbing last after a filling?
Numbness after a filling usually lasts about 1 to 3 hours, but it can sometimes continue for several hours depending on the anaesthetic used and the area treated. Injections in the lower jaw often last longer than in the upper teeth.
- Do not chew until the numbness has mostly worn off.
- Be careful with hot drinks so you do not burn your lip or tongue.
- Call the clinic if numbness lasts unusually long or feels worse instead of fading.

How soon can I eat after a dental filling?
If local anesthesia was used, wait until numbness wears off to avoid biting your cheek or tongue. For composite fillings, eating is usually possible soon after treatment, but avoid very hard foods on the treated side for the first day.
Is tooth sensitivity normal after a new filling?
Mild sensitivity to cold, pressure, or sweets can happen for a short period. It usually improves within days to weeks. If pain worsens or biting feels uneven, contact your clinic for an adjustment.
How long after a filling can you eat?
You can typically eat immediately after a composite (tooth-colored) filling, as the material is hardened instantly with a UV light. However, if your dentist used a local anesthetic, it is crucial to wait until the numbness wears off to avoid accidentally biting your tongue or cheek. - Wait at least 1–2 hours for the anesthesia to wear off completely. - Avoid extremely hot or cold foods if you experience temporary post-treatment sensitivity. - Chew on the opposite side of the filling for the first 24 hours to let the area settle.
Can you eat after a filling?
Yes, you can eat after a filling, but the timing depends on the type of material used for the restoration. Composite resin fillings harden instantly, allowing for immediate eating, while silver amalgam fillings may require waiting up to 24 hours to fully set. - Test your bite with soft foods like yogurt or soup before moving to harder textures. - Be cautious with sticky foods that could potentially dislodge a fresh restoration. - Avoid chewing until the numbness from the local anesthetic has completely dissipated.
