How long does a filling take?
Whether you’re trying to fit the appointment into your lunch break or you’re simply feeling nervous about the procedure, knowing what to expect can make the experience much less stressful.
The good news is that most dental fillings are completed within 20 to 60 minutes, depending on the size of the cavity, its location and the type of filling being used.
If you’ve been searching how long does a filling take at the dentist, how long do dental fillings take, or how long does a small filling take, here’s everything you need to know.
How long does a filling take?
For most patients, a single filling takes between 20 and 60 minutes.
Smaller cavities are usually completed much more quickly, while larger or more complex fillings naturally require extra time.
Your appointment may also include:
- A dental examination
- X-rays if required
- Local anaesthetic
- Bite adjustments
- Aftercare advice
These steps are all included within your overall appointment time.
How long does a filling take at the dentist?
Many people ask how long does a filling take at the dentist?
The answer depends on several factors, including:
- The size of the cavity
- The location of the tooth
- The filling material
- Whether local anaesthetic is needed
- The number of teeth being treated
For a straightforward filling, many patients are in and out of the surgery within an hour.
How long do dental fillings take?
If you’re wondering how long do dental fillings take, here is a general guide.
| Type of Filling | Typical Treatment Time |
|---|---|
| Small filling | 20 to 30 minutes |
| Medium filling | 30 to 45 minutes |
| Large filling | 45 to 60 minutes |
| Complex filling | 60 to 90 minutes |
Every patient is different, so your dentist will give you a more accurate estimate after examining your tooth.
How long does a small filling take?
One of the most searched questions is how long does a small filling take?
For a small cavity that only affects the outer part of the tooth, treatment usually takes around 20 to 30 minutes.
These fillings often require minimal preparation and are among the quickest procedures performed in general dentistry.
How long do fillings take at the dentist if you have multiple cavities?
If you need more than one filling, your appointment will naturally take longer.
As a general guide:
- Two fillings may take around 45 to 75 minutes.
- Three fillings may take 60 to 90 minutes.
- Four or more fillings may require multiple appointments.
Many dentists prefer completing several fillings during the same visit where possible, reducing the number of trips to the practice.
What affects how long a filling takes?
Every filling is slightly different.
Several factors influence the treatment time.
Size of the cavity
Small cavities require less drilling and less filling material.
Larger cavities take longer because more decay must be removed and additional layers of filling material may be needed.
Location of the tooth
Back teeth are generally more difficult to reach than front teeth.
Fillings between teeth or near the gum line may also take longer because they require greater precision.
Type of filling
Composite (white) fillings are the most common choice in UK dental practices.
They are placed in layers, with each layer hardened using a special curing light.
This process can take slightly longer than placing traditional amalgam fillings.
Local anaesthetic
If your tooth requires numbing, your dentist will allow a few minutes for the anaesthetic to take effect before beginning treatment.
Although this adds a little time, it makes the procedure much more comfortable.
What happens during a filling appointment?
Knowing what happens can make the appointment feel less daunting.
Most fillings follow these simple steps.
1. Examination
Your dentist examines the tooth and may take an X-ray to assess the extent of the decay.
2. Local anaesthetic
If needed, the area is numbed to ensure you remain comfortable throughout the procedure.
3. Removing the decay
The damaged part of the tooth is carefully removed using dental instruments.
4. Placing the filling
The chosen filling material is placed into the cavity.
For composite fillings, this is done in several layers, with each layer cured using a blue light.
5. Shaping and polishing
Your dentist shapes the filling so it fits naturally with your bite before polishing it to create a smooth finish.
6. Bite check
Finally, you’ll be asked to bite together to ensure the filling feels comfortable.
Minor adjustments can be made immediately if necessary.
How long does numbness last after a filling?
If you’ve had local anaesthetic, your lips, cheeks or tongue may remain numb for 2 to 4 hours.
During this time, it’s best to:
- Avoid chewing until the numbness wears off.
- Be careful not to bite your lips or cheeks.
- Choose softer foods if you’re hungry.
Can I return to work after a filling?
Yes.
Most people return to work, university or their usual daily routine immediately after treatment.
If you’ve had local anaesthetic, speaking may feel slightly unusual until the numbness disappears, but this settles within a few hours.
How long does it take to recover after a filling?
Recovery is usually very quick.
Some patients experience mild sensitivity to:
- Hot drinks
- Cold foods
- Sweet foods
- Biting pressure
This generally improves over a few days.
If discomfort lasts longer than two weeks or becomes more severe, contact your dentist for a review.
