If your dentist has told you that you need a filling, you’re probably wondering one thing before anything else.
Do fillings hurt?
It’s one of the most common concerns patients have, especially if they haven’t had dental treatment before.
The reassuring news is that modern cavity fillings are usually far less uncomfortable than most people expect. Thanks to local anaesthetic and modern dental techniques, most patients feel pressure or vibration rather than pain during the procedure.
If you’re asking does getting a filling hurt, does getting a cavity filled hurt, or do teeth fillings hurt, here’s what you can realistically expect.
Do fillings hurt?
For most people, no.
Before your dentist starts removing the decay, they’ll usually numb the tooth and surrounding area with a local anaesthetic.
Once the anaesthetic has taken effect, you shouldn’t feel pain.
Instead, you may notice:
- Pressure
- Gentle pushing
- Vibrations from the dental drill
- Water spray
- Mild pulling sensations
These feelings are completely normal and don’t usually indicate that anything is wrong.
Does getting a filling hurt?
Many patients ask, does getting a filling hurt?
The answer depends on how deep the cavity is and whether local anaesthetic is used.
For the majority of fillings:
- The injection itself feels like a small pinch.
- The area becomes numb within a few minutes.
- The filling procedure is generally comfortable.
- Most patients are surprised by how little they actually feel.
Many people say the anxiety beforehand is worse than the treatment itself.
Does getting a cavity filled hurt?
If you’ve been wondering does getting a cavity filled hurt, the answer is usually no.
In fact, untreated cavities often hurt far more than the filling used to repair them.
Once your tooth is numb, your dentist removes the decayed area and replaces it with a filling material that restores the tooth’s strength and function.
For many patients, the procedure actually provides relief from ongoing toothache.
Do teeth fillings hurt afterwards?
Some mild discomfort after treatment is perfectly normal.
You may notice:
- Sensitivity to hot drinks
- Sensitivity to cold foods
- Mild tenderness when biting
- Slight soreness around the injection site
These symptoms usually improve within a few days.
Over-the-counter pain relief is often enough if any discomfort develops.
When are fillings more likely to feel uncomfortable?
Although most fillings are straightforward, some situations may cause temporary sensitivity afterwards.
These include:
- Deep cavities close to the nerve
- Very large fillings
- Multiple fillings completed during one visit
- Teeth with existing cracks
Even in these situations, the discomfort usually settles as the tooth heals.
Do fillings hurt without an injection?
One of the most searched questions is do fillings hurt without an injection?
The answer depends on the size and location of the cavity.
For very small cavities limited to the outer enamel, some patients can comfortably have treatment without local anaesthetic.
However, once decay reaches the dentine, which is the softer layer beneath the enamel, treatment becomes much more sensitive.
For this reason, dentists often recommend an injection to keep you comfortable.
If you’re nervous about injections, let your dentist know. They can often apply a numbing gel beforehand so you barely feel it.
Does tooth drilling hurt without anaesthesia?
Another common question is does tooth drilling hurt without anaesthesia?
If the tooth still has healthy, sensitive nerve tissue and the drilling reaches dentine, it can be uncomfortable without anaesthesia.
Modern local anaesthetic allows dentists to carry out treatment while keeping the area numb, which is why it is routinely offered for most fillings.
In situations where the cavity is very small, your dentist may discuss whether anaesthetic is actually necessary.
What does the injection feel like?
For many people, the injection is the part they worry about most.
In reality, it usually lasts only a few seconds.
You may feel:
- A small scratch
- Mild pressure
- A slight stinging sensation
After that, the area gradually becomes numb, making the rest of the treatment much more comfortable.
How long does numbness last?
Most local anaesthetic lasts between 2 and 4 hours, depending on the type used.
During this time:
- Avoid chewing until feeling returns.
- Be careful not to bite your lips or cheeks.
- Choose softer foods if needed.
Once the numbness wears off, you can usually return to your normal routine.
When should you contact your dentist?
Some sensitivity after a filling is normal.
However, you should arrange a review if you notice:
- Pain lasting longer than two weeks
- Sharp pain when biting
- Swelling
- Persistent throbbing pain
- A filling that feels too high
- Difficulty chewing comfortably
Sometimes a simple bite adjustment is all that’s needed to solve the problem.
Tips for reducing anxiety before a filling
If you’re nervous about dental treatment, you’re certainly not alone.
Many patients find it helpful to:
- Tell the dentist they’re anxious.
- Arrange a morning appointment.
- Listen to music during treatment.
- Agree on a hand signal if they need a short break.
- Practise slow, steady breathing.
Dentists treat nervous patients every day and will usually be happy to work at a pace that helps you feel comfortable.
Frequently Asked Questions

Do teeth fillings hurt afterwards?
Some mild sensitivity is common for a few days, especially when eating hot or cold foods. This usually improves on its own.
Do fillings hurt without an injection?
Very small fillings sometimes don’t require an injection. However, deeper cavities are usually much more comfortable when local anaesthetic is used.
Does tooth drilling hurt without anaesthesia?
It can, particularly if the decay has reached the dentine. This is why dentists generally recommend local anaesthetic for most cavity fillings.
