With effective local anaesthetic, dental treatment should not cause sharp pain. You may still notice pressure, vibration, pulling or movement, and you should tell the clinician immediately if you feel pain.
Numbing and sedation do different jobs
Local anaesthetic blocks pain signals in the treatment area while you remain awake. Sedation reduces fear, awareness or memory but does not usually numb the tooth by itself. Sedated patients commonly receive local anaesthetic as well.
Anaesthesia and sedation options
| Option | What it does | Important points |
|---|---|---|
| Topical anaesthetic gel | Numbs the gum surface before an injection | Reduces needle sensation but is not enough for drilling or surgery |
| Local anaesthetic injection | Numbs a tooth or area of the mouth | You remain awake and may feel pressure or vibration |
| Nitrous oxide | Creates light relaxation | Local anaesthetic is still normally needed |
| Oral sedative | Reduces anxiety and causes drowsiness | Requires screening, an escort and activity restrictions |
| IV conscious sedation | Produces deeper relaxation and limited memory | You are not normally fully unconscious; monitoring is essential |
| General anaesthesia | Makes you unconscious | Used selectively in an appropriately equipped medical setting |
Pain and recovery comparison by procedure
| Procedure | During treatment | Common afterwards | Typical home-care focus |
|---|---|---|---|
| Check-up and cleaning | Usually no anaesthetic; sensitivity may occur | Mild gum tenderness | Gentle brushing and desensitising advice if recommended |
| Filling | Local anaesthetic for deeper work; pressure/vibration possible | Brief sensitivity or bite tenderness | Do not chew until numbness passes; request a bite adjustment if needed |
| Composite bonding | Often little or no anaesthetic for additive work | Minor gum or bite awareness | Avoid biting hard objects; report a high bite |
| Veneer or crown | Local anaesthetic commonly used for preparation | Sensitivity and gum tenderness | Protect temporaries and report looseness or worsening pain |
| Root canal | Local anaesthetic; should feel similar to other routine treatment | Tenderness for several days | Avoid heavy biting until restored; seek review if symptoms worsen |
| Extraction | Local anaesthetic blocks pain; pressure and movement are expected | Soreness, swelling and possible bruising | Protect the blood clot; avoid smoking, forceful rinsing and hot food initially |
| Wisdom-tooth surgery | Local anaesthetic, sometimes with sedation | Swelling often peaks around days two or three | Soft diet, prescribed cleaning routine and monitoring for dry socket/infection |
| Dental implant placement | Local anaesthetic, with optional sedation in selected cases | Soreness and swelling during early healing | Follow surgical hygiene and diet instructions; avoid loading the site |
| Deep gum cleaning | Local anaesthetic may be used | Sensitivity and gum tenderness | Meticulous but gentle plaque control and scheduled reassessment |
| Gum graft or bone graft | Local anaesthetic; sedation may be offered | More substantial tenderness and swelling | Protect the graft and follow food, brushing and medicine instructions exactly |
What should you say if you feel pain?
Agree on a stop signal before treatment. If you feel sharp pain, raise your hand and ask the dentist to stop. The clinician can test numbness, wait longer, add anaesthetic or use a different technique. Anxiety should never be used to dismiss genuine pain.
Why an infected tooth can be harder to numb
Severe inflammation can make predictable anaesthesia more difficult, particularly in some lower molars. This does not mean treatment should simply continue painfully. The dentist may use supplementary injections, staged treatment or specialist referral.
Home care after local anaesthetic
- Do not chew your cheek, lip or tongue while numb.
- Avoid very hot food and drink until normal sensation returns.
- Take only medicines recommended for you and follow the written dose.
- Choose softer food when surgery or extensive preparation makes chewing uncomfortable.
- Do not exceed medication limits or combine products containing the same ingredient.
- Keep the clinic’s urgent contact details and treatment records.
Home care after extraction or surgery
- Follow the clinic’s written bleeding-control instructions.
- Avoid vigorous rinsing, spitting or disturbing the socket during the initial clot-forming period.
- Do not smoke; it delays healing and increases complication risk.
- Use any prescribed mouthwash only when instructed to start it.
- Plan recovery days locally rather than flying immediately.

When to seek urgent help
Urgent assessment is needed for breathing or swallowing difficulty, heavy uncontrolled bleeding, rapidly increasing swelling, fever, pus, an allergic reaction or severe uncontrolled pain. Contact the treating clinic for pain that is worsening rather than improving, a high bite, a loose temporary or persistent numbness.
