How Long After a Tooth Filling Can You Eat? (Wait Times & Recovery Guide)

A tooth filling is one of the most common dental procedures, used to restore a tooth that has been damaged by decay. Once the cavity has been cleaned and filled, one of the first questions patients ask is: how long after a tooth filling can you eat? The answer depends on several factors, including the type of filling material used and whether local anaesthetic was administered during the procedure.

This guide covers recommended wait times, what foods to choose, and what to expect during recovery — so you can return to eating comfortably with confidence.

Quick Answer: How Long After a Tooth Filling Can You Eat?

In most cases, patients can eat after a filling once any numbness from local anaesthetic has fully worn off. For composite (white) fillings, the material is set during the appointment using a curing light, meaning there is typically no additional wait for the filling itself. Amalgam fillings may require a longer period before eating on the treated side.

• Composite (white) fillings — often safe to eat once numbness has worn off, as the material is light-cured during the procedure
• Amalgam fillings — may require a longer wait, as the material takes additional time to fully set
• Avoid chewing until full feeling has returned to the lips, cheeks, and tongue
• Follow your dentist’s specific advice, as recommendations may vary depending on the size and position of the filling

The type of filling material and the complexity of the procedure both play a role in how soon you can eat comfortably. Your dentist will provide personalised guidance at the end of your appointment.

Can You Eat After a Filling Tooth If It’s Still Numb?

It is generally advisable to wait until numbness has fully worn off before eating. Local anaesthetic temporarily reduces sensation in the treated area, including the lips, cheeks, and tongue, which can affect your ability to chew safely and detect temperature.

• Risk of biting the lip, cheek, or tongue without realising, potentially causing injury
• Reduced awareness of pressure, which may lead to biting down too hard on the treated tooth
• Difficulty judging food temperature, increasing the chance of burning the mouth

Numbness typically takes between one and three hours to wear off, depending on the type and amount of anaesthetic used. During this time, it is usually best to avoid eating solid foods. If you need to drink, room-temperature water or a lukewarm drink is a sensible choice. Once sensation has fully returned, you can begin eating — starting with softer foods if the area feels tender.

How Long Does a Filling Take?

A straightforward filling appointment typically takes between 20 and 40 minutes. However, the exact duration depends on the size and location of the cavity, the filling material used, and whether any additional procedures such as X-rays are required.

• Small filling — typically a shorter appointment, often completed within 20 to 30 minutes
• Larger filling — may take longer, particularly if the decay is more extensive or the tooth requires careful preparation
• Multiple fillings — treating more than one tooth in a single visit extends the overall appointment time
• X-rays or additional procedures — diagnostic imaging or other assessments may add time to the visit

Patients sometimes wonder how long does a fill take when planning their day around an appointment. While most general dentistry fillings are completed relatively quickly, it is worth allowing a little extra time in case the procedure takes longer than expected. Your dental team will be able to give you an estimate when you arrive.

What Can You Eat After a Filling?

Once any numbness has worn off and you feel ready to eat, it is generally a good idea to start with softer foods and gradually return to your normal diet. Being mindful of what you eat in the hours following a filling can help protect the restoration and minimise any discomfort.

• Soft foods — soups, yoghurt, scrambled eggs, mashed vegetables, and pasta are gentle choices for the first meal
• Avoid very hot foods and drinks if your mouth is still numb, to prevent accidental burns
• Avoid very hard or sticky foods immediately after the procedure — such as nuts, toffee, or hard sweets — as these may place excessive pressure on the new filling
• Chew on the opposite side if your dentist has advised this, particularly for larger fillings

These are common-sense guidelines rather than strict rules. Your dentist may offer specific recommendations based on the type and location of the filling. If in doubt, softer foods and room-temperature drinks are a safe starting point.

When Can I Eat Normally After a Filling?

Most patients can return to eating normally within a day or so of having a filling, although this varies depending on the individual and the procedure. The key indicators that you are ready to eat normally include full return of sensation, no significant discomfort when biting, and no specific restrictions from your dentist.

• Numbness has fully worn off — you can feel the treated area and surrounding tissues normally
• No discomfort when biting — you can chew without pain or an uneven feeling in the bite
• No specific restrictions from your dentist regarding diet or chewing

It is worth noting that mild sensitivity — particularly to hot, cold, or sweet foods — can occur for a few days after a filling and does not necessarily indicate a problem. This typically settles on its own. If sensitivity persists beyond a couple of weeks or interferes with eating, it is advisable to contact your dentist for a review.

Is It Normal for a Filling to Feel Sensitive?

Some degree of sensitivity after a filling is common and is usually temporary. The tooth has been treated and the surrounding tissues may be slightly irritated from the procedure, which can result in heightened awareness of temperature, pressure, or sweetness for a short period.

• Mild sensitivity to pressure when biting down, which often improves within a few days
• Temporary temperature sensitivity, particularly to cold foods and drinks
• A slight bite adjustment period, where the tooth feels slightly different as you adapt to the new filling

In most cases, this sensitivity settles naturally as the tooth adjusts. Using a toothpaste designed for sensitive teeth may offer some relief during this period. However, if pain is severe, gets worse over time, or does not improve within a couple of weeks, it is important to contact your dental practice for assessment. Persistent symptoms may indicate that the filling needs a minor adjustment or further evaluation.

What If My Bite Feels High After a Filling?

A “high bite” occurs when the filling sits slightly above the natural level of the tooth surface, causing the treated tooth to make contact before the surrounding teeth. This can result in discomfort when chewing, jaw soreness, or a general feeling that something is not quite right when you close your mouth.

• Feeling of uneven contact — one tooth seems to touch before the others when biting
• Discomfort when chewing, particularly on harder foods
• Jaw soreness or muscle tension that develops after the appointment

A high bite can sometimes be difficult to detect during the appointment itself, as the anaesthetic may affect how you perceive your bite at the time. If you notice uneven contact once the numbness has worn off, contact your dentist. A minor adjustment — which is a straightforward and usually painless procedure — can resolve the issue. Leaving a high bite unadjusted may lead to ongoing discomfort, so it is best to have it checked promptly.

When Should I Contact the Dentist After a Filling?

While some mild sensitivity is expected, there are certain signs that warrant professional review. If you experience any of the following after a filling, it is advisable to contact your dentist for guidance.

• Severe or worsening pain that does not respond to over-the-counter painkillers
• Swelling around the treated tooth or in the surrounding gum tissue
• Difficulty chewing or a persistent feeling that the bite is uneven
• Persistent numbness that lasts significantly longer than expected after the anaesthetic

These symptoms are not common, but they can indicate that the filling needs attention — whether through a minor adjustment, additional treatment, or further investigation. Your dentist is best placed to assess the situation and advise on the appropriate next steps. Do not hesitate to contact your dental practice if something does not feel right.
