Once you have completed your root canal treatment in Dreghorn, the hardest part is behind you. The infection has been cleared, the canals cleaned and sealed, and the tooth is on its way to recovery. But how you look after the tooth in the days, weeks, and months that follow has a significant bearing on how well it heals and how long it continues to serve you. Good aftercare is not complicated, but understanding the reasons behind each recommendation helps you follow through consistently.
Most patients find the recovery from root canal treatment to be far more comfortable than they anticipated. Modern techniques and the fact that the source of infection has been removed mean that post-treatment discomfort is usually mild and short-lived. With a little care and attention, you should be back to eating, drinking, and going about your daily life with minimal disruption within a few days.
The First 24 to 48 Hours
Immediately after treatment, your mouth will still be numb from the local anaesthetic. Take care not to bite your cheek, lip, or tongue while this numbness persists — it is easy to do so accidentally when you cannot feel the area properly. Wait until full sensation has returned before eating on the treated side.
Some soreness and tenderness around the tooth are completely normal in the first couple of days, particularly when biting down. This is your body’s natural response to the procedure — the tissues around the root tip may be slightly inflamed as part of the healing process. As the NHS advises, over-the-counter painkillers such as paracetamol or ibuprofen are usually sufficient to manage any discomfort in the initial period. Follow the dosage instructions on the packaging and avoid aspirin if you are under 16 or have been advised not to take it.
During the first 48 hours, try to:
- Avoid chewing on the treated side of your mouth
- Stick to soft foods that do not require significant pressure to eat
- Avoid very hot drinks, which can increase sensitivity
- Avoid alcohol if you have been prescribed antibiotics
- Get adequate rest — healing is supported by good sleep and reduced stress
Managing Sensitivity and Soreness
Sensitivity around the treated tooth is expected and is not a sign that something has gone wrong. The slight discomfort you experience when biting or pressing on the area is a normal part of the healing process as the tissues settle. For most patients, this fades noticeably within two to three days and resolves entirely within a week or two.
If the pain is severe, worsening rather than improving after a few days, or accompanied by swelling or a return of symptoms you had before treatment, contact your dentist. Occasionally, a small flare-up can occur during healing — this is known and manageable — but significant deterioration is worth reporting so that your dentist can assess whether any additional treatment is needed.
Anti-inflammatory painkillers like ibuprofen are particularly useful in the early days because they address both pain and the underlying inflammation. If you are unable to take ibuprofen for any reason, paracetamol is a good alternative. Avoid taking both at the same time unless specifically directed to do so by a healthcare professional.
Diet Guidance After Root Canal Treatment
What you eat in the days and weeks after root canal treatment matters more than you might think. The tooth that has been treated is temporarily more vulnerable than a fully restored tooth, particularly if it is still awaiting a permanent crown. A tooth without a crown can be more prone to fracture, and excessive pressure from hard or crunchy foods can crack the tooth structure before it has been properly protected.
In the immediate recovery period, choose foods that are soft and easy to eat:
- Porridge, scrambled eggs, and yoghurt for breakfast
- Soups, mashed potato, and soft-cooked vegetables
- Pasta, rice, and other soft grains
- Soft fish, tender meat, or well-cooked pulses
- Bananas, avocado, and other naturally soft fruits
Foods to avoid, at least until the crown has been fitted and for a short period afterwards:
- Hard bread crusts, bagels, and baguettes
- Crunchy raw vegetables like carrots or celery
- Sticky sweets, toffees, and chewing gum
- Nuts and hard seeds
- Ice (chewing ice is particularly harmful to teeth)
Oral Hygiene After Treatment
Good oral hygiene should continue as normal after root canal treatment, and in fact it is more important than ever. Keeping the area clean helps prevent further infection and supports healthy healing. Brush your teeth twice a day with a fluoride toothpaste, being gentle around the treated tooth in the first day or two if the area is tender, and continue to use floss or interdental brushes as part of your routine.
You do not need to avoid cleaning around the treated tooth — quite the opposite. The gum around the tooth needs to be kept free of plaque just like anywhere else in your mouth. If you use an antibacterial mouthwash, continue to do so as directed, but avoid using very hot rinses directly after treatment while the area is still sensitive.
Avoiding Chewing on the Treated Side Until the Crown Is Fitted
This is one of the most important aspects of root canal aftercare, and one that is sometimes overlooked. Once the root canal procedure itself is complete, the tooth typically has a temporary filling or dressing in place. This material is sufficient to seal the tooth between appointments but is not designed to withstand the full forces of chewing. Biting hard on the treated side before the crown is fitted risks fracturing the remaining tooth structure, which could compromise the treatment and even result in the tooth being lost.
Try to develop the habit of chewing predominantly on the opposite side of your mouth until your permanent crown has been fitted and cemented. It may feel a little awkward at first, but it is a worthwhile precaution that protects the work already done and gives the tooth the best chance of a successful long-term outcome.
The Importance of the Crown
After root canal treatment, the tooth is structurally weakened. The pulp — which in a living tooth provides moisture and nutrients to the surrounding dentine — has been removed, and without it the tooth can become more brittle and prone to cracking under normal biting forces. A dental crown is placed over the treated tooth to encircle and protect it entirely, distributing biting forces evenly and preventing the tooth from splitting.
Fitting the crown is not merely cosmetic — it is a clinically important step in completing the treatment. Studies consistently show that teeth with root canal treatment that are restored with a crown have significantly higher long-term survival rates than those restored with a filling alone, particularly in back teeth that experience greater chewing forces. If a crown is recommended following your treatment, it is worth prioritising this appointment and not leaving the temporary restoration in place longer than necessary.
Long-Term Maintenance and When to Contact Your Dentist
| Timeframe | What to Expect | Action Required |
|---|---|---|
| First 24–48 hours | Numbness wearing off; mild soreness when biting | Soft diet; avoid treated side; take painkillers if needed |
| Days 3–7 | Soreness subsiding; sensitivity reducing | Resume normal eating gradually; avoid very hard foods |
| Weeks 1–4 | Tooth should feel settled; temporary filling in place | Attend crown fitting appointment as scheduled |
| After crown fitting | Tooth fully restored and protected | Resume normal diet; maintain regular oral hygiene |
| Long term | Tooth functions normally | Attend regular dental check-ups; maintain excellent hygiene |
In the long term, a root-canal-treated tooth cared for properly can last as long as a natural tooth. Attend your regular dental check-ups so that the crown and surrounding gum can be monitored, and maintain a thorough daily oral hygiene routine. If at any point you notice a return of pain, swelling, or any unusual symptoms around the treated tooth, contact your dentist promptly rather than waiting for your next scheduled visit.
