This is one of the most searched dental questions on the internet, and it’s worth answering honestly rather than pretending all dental treatment is painless. The reality is more nuanced than the fear, and understanding it tends to reduce anxiety rather than increase it.
The procedures people fear the most
Root canal treatment tops every fear list, but the reality rarely matches the reputation. A root canal removes the infected pulp from inside a tooth and seals the canals. Done under local anaesthetic — which is standard — the procedure itself is typically no more uncomfortable than a filling. The tooth is numb. What patients experience is pressure and duration, not pain.
The root canal myth comes from a time before effective anaesthesia, when the procedure genuinely was painful. That was decades ago. Modern root canal treatment is one of the most technically improved procedures in dentistry.
What actually tends to hurt the most
Surgical wisdom tooth extraction tends to rank highest for post-operative pain. Removing impacted lower wisdom teeth involves cutting through gum tissue and sometimes removing bone. The procedure is performed under local anaesthetic, but the recovery — typically three to five days of significant soreness and swelling — is what patients remember. This is one of the few procedures where post-operative pain genuinely matches the anticipation. For urgent extractions in London, see our emergency dentist guide.
Deep scaling and root planing (treatment for advanced gum disease) can be uncomfortable because it involves cleaning below the gumline, often across multiple quadrants of the mouth. The procedure is done under local anaesthetic, but the area treated is larger and the recovery can involve several days of sensitivity.
Multiple extractions in one session can be more taxing than a single extraction simply because of the duration and accumulated trauma to the surrounding tissue.
Dental implant placement is surprisingly low on the pain scale for most patients. The bone where the implant is placed has fewer pain receptors than the gum tissue around it, and most patients report less discomfort than they anticipated. The cost of implants in London is covered in detail in our dentist cost guide.
Why it hurts less than you think
Three things have changed since dental treatment earned its painful reputation. Anaesthetics are far more effective and faster-acting than they were. Dentists are better at managing patient anxiety, which itself reduces perceived pain. And techniques have improved — procedures that once required significant tissue removal are now far more conservative.
The single biggest factor in how much a procedure hurts is whether you went in early or late. A small cavity filled early is a five-minute numb procedure. The same tooth left until it abscesses means emergency treatment, possible extraction, and a recovery that actually does hurt. Patients who fear dental pain and therefore avoid the dentist tend to end up experiencing far more of it.
What to do if you’re anxious about pain
Tell your dentist. Dentists can adjust anaesthetic dosages, offer sedation options (from oral sedation to IV sedation for significant anxiety), and work at a pace that suits you. Many practices in Camden, Islington, and Hackney offer dedicated anxious patient appointments. Asking about pain management options before your appointment, not during it, gives you and your dentist more options to work with.
