This guide covers how much pain is normal and the signs that point to something more serious. You’ll also learn what to do if the pain isn’t getting better, and whether it could entitle you to compensation.
Yes, some discomfort and pain are expected after most dental work. Your gums may feel tender, or your jaw might ache from being held open for a while. Your teeth may also feel sensitive to hot or cold for a short time afterwards, especially with restorative treatments such as crowns and fillings.
Local anaesthetic wearing off can cause a dull ache when feeling returns to the area. This is a normal part of how your mouth responds to dental treatment. The more invasive the treatment, such as a root canal, the more likely you may feel some pain afterwards. But post-treatment pain is usually mild to moderate, and should ease during the following days.
Your dentist is also expected to have warned you about this kind of expected discomfort and pain as part of getting your informed consent before treatment.
If you’re wondering how long pain should last after dental treatment, the answer is that it depends on the procedure and on how pain sensitive you are. While everyone is different, here are some general guidelines:
Pain that runs well past these general timeframes is often one of the first things a solicitor or an independent dental expert will look at when assessing whether your treatment fell below an acceptable standard of care. And if it did, ongoing pain itself may form the basis of a compensation claim.
Pain that gets worse instead of better, day after day, is one of the warning signs that something has gone wrong with your dental treatment. Normal healing pain tends to fade gradually. But pain linked to an underlying problem typically builds and gets worse.
Other signals that your pain isn’t normal healing include:
None of these signs mean that your dentist was negligent, but they could. And unexpected or ongoing pain is a strong enough reason to get the treatment looked at properly rather than assuming it will pass.
It could be, particularly if the pain feels different from ordinary soreness. A numb or tingling feeling in your lip or tongue can be a sign of nerve damage. Some people notice a burning sensation in the chin instead, or sharp pain that shoots in and comes back unpredictably. Loss of taste, or a strange sensation when you eat or speak can also point to nerve damage.
Nerve damage or temporary irritation can be common in extractions, root canals, or implant procedures. Nerves sit close to the roots of your back teeth and to the jawbone itself. That’s why procedures like wisdom tooth removal and implant surgery carry a higher risk of this kind of injury than a routine filling does.
Your dentist should have warned you about the risk of nerve damage before the procedure. If they didn’t, that failure to obtain your informed consent may support a claim, even if your dentist carried out the procedure correctly.
Not necessarily. New dental work can feel slightly odd for a few days while your bite adjusts, and some sensitivity to temperature is also normal during that time. Your gums may feel tender around a new crown or bridge as they get used to it.
But if you feel constant pressure, pain when chewing, or a bite that doesn’t settle even weeks after fitting, something is wrong. These symptoms can be a sign that the crown or bridge wasn’t fitted or shaped correctly, or that it’s sitting too high against your other teeth. A dentist can usually spot this quickly by checking how your teeth meet when you bite down.
A crown or bridge fitted poorly is generally treated as substandard workmanship, and can give grounds for a dental negligence claim.
Throbbing pain that gets worse when you bite down often points to infection. Further signs can include swelling in your gum or cheek, a bad taste, or a low-grade fever alongside the pain.
Painful infections may develop when your dentist didn’t clean or seal a filling properly, which lets bacteria back into the tooth. Infections can also follow an extraction if debris was left behind, or the socket wasn’t properly cleaned out.
Left unchecked, this kind of infection tends to get worse rather than better. If your dentist doesn’t spot an infection in time, it can spread past the original tooth and cause further health complications, such as an abscess. When an infection develops unchecked due to a dentist’s mistake, they likely breached the standard of care a competent dentist should have provided.
A few practical steps can help you work out what’s going on with your treatment:
Bringing along a written record of your symptoms makes it easier for a second dentist, or later a solicitor, to see the full picture. It can also help to rule out normal healing as an explanation, so you’re not left guessing if the pain and discomfort you’re experiencing is expected.
Resist the temptation to self-medicate your way through persistent pain with over-the-counter painkillers alone. Masking the pain doesn’t fix the underlying issue, and can delay getting the treatment you need.
Compensation for pain after dental treatment is a part of dental negligence claims, even without lasting physical damage. The law recognises that unnecessary pain caused by substandard dental treatment is a harm in its own right, separate from any further dental work you might also need.
Say an infection was left to develop because a root canal wasn’t properly cleaned. The weeks of avoidable pain you went through can be reflected in your compensation, alongside the cost of putting things right.
Compensation can also cover any time off work if the pain affected your job, plus travel costs for extra appointments. The exact figure you could receive will depend on how long the pain lasted and how badly it affected your daily life.
Yes, especially once you’ve had a second opinion and the pain still hasn’t improved or is affecting your daily life. A solicitor can look at your pain history and your dental records. They can also engage an independent dental expert to find out if your dentist was negligent. You’ll discover whether your pain is likely to support a claim, or whether it looks like a normal part of recovery.
Don’t wait too long to get help. Under the Limitation Act 1980, you generally have three years to bring a dental negligence claim. But the sooner you contact a solicitor, the better for your claim, as evidence will be easier to collect.
