Getting a dental filling is a routine procedure to restore damaged or decayed teeth. However, what you do after the filling is just as important as the procedure itself. Knowing what to avoid can ensure the success of your filling, protect your oral health, and minimize discomfort. Below is a comprehensive guide on what to steer clear of after receiving dental fillings.
1. Avoid Chewing on the Filling Immediately
Why It’s Important
After receiving a filling, the material used may take time to set completely. For amalgam (silver) fillings, this process can take up to 24 hours. Though composite (tooth-colored) fillings harden quickly under UV light, exercising caution in the first few hours can prevent undue pressure on the treated tooth.
What to Do Instead
Stick to soft foods and chew on the opposite side of your mouth until:
- 24 hours have passed for amalgam fillings.
- The numbness fully wears off for composite fillings, so you don’t accidentally bite your cheeks or tongue.
2. Avoid Eating Hard or Sticky Foods
The Risk
Hard foods like nuts, seeds, or candies can crack or dislodge a fresh filling. Sticky foods such as caramel, chewing gum, or dried fruits can pull at the filling, risking its stability.
Pro Tip
Opt for softer options such as mashed potatoes, yogurt, or soups during the first few days after the procedure. Gradually reintroduce harder foods as your dentist advises.
3. Don’t Consume Hot or Cold Beverages Immediately
Sensitivity Concerns
Fillings can make teeth more sensitive to temperature changes, especially if the cavity was deep. Consuming hot coffee or ice-cold water too soon may irritate the nerve and lead to discomfort.
Suggested Approach
Stick to lukewarm beverages and avoid extreme temperatures until sensitivity subsides, which typically resolves in a few days to a week.

4. Avoid Clenching or Grinding Your Teeth
Why It’s Harmful
Bruxism (teeth grinding) can exert significant pressure on newly placed fillings, leading to cracks or premature wear. It can also lead to lingering pain and discomfort in the treated tooth.
How to Address It
If you’re prone to grinding your teeth or clenching your jaw, consider using a nightguard or consulting your dentist for preventive measures.
5. Don’t Skip Proper Oral Hygiene
The Misconception
Some people avoid brushing or flossing near the treated area out of fear of dislodging the filling. However, neglecting oral hygiene can lead to further decay and compromise the filling.
The Right Way
Brush gently near the filling using a soft-bristled toothbrush. Use waxed floss to prevent snapping or getting stuck, but ensure you clean thoroughly between the teeth.
6. Avoid Introducing Alcohol-Based Mouthwashes
Potential Irritation
Alcohol-based mouthwashes may irritate the treated area, especially if the surrounding gums are sensitive following the procedure.
Alternative Option
Switch to an alcohol-free mouthwash or rinse with warm saltwater twice daily to promote healing and reduce inflammation.
7. Don’t Ignore Lingering Discomfort
When It’s Normal
It’s typical to feel mild discomfort or sensitivity to pressure, temperature, or sweetness for a few days to a week after getting a filling.
When to Act
If the pain intensifies or lasts longer than one week, there could be issues such as:
- High filling (where the filling protrudes and needs adjustment).
- Nerve irritation from deep cavities.
- Signs of infection.
Contact your dentist immediately if discomfort persists.
8. Avoid Smoking or Tobacco Use
Harmful Effects
Smoking or using tobacco products can slow down the healing process and increase the risk of infections. It can also stain composite fillings, affecting the aesthetic appearance.
What to Consider
This might be a good time to quit tobacco entirely. Seek support from dental professionals if needed.
9. Don’t Bite on Non-Food Items
The Habit’s Impact
Chewing on pens, fingernails, or other objects puts undue pressure on your fillings. This can lead to damage, especially in the first few days after the procedure.
Focus on Awareness
Be mindful of these habits and try to redirect your attention to break them.
10. Avoid Overlooking Follow-Up Visits
Why It Matters
After your filling, your dentist may schedule a follow-up appointment to ensure everything is aligned and functioning as it should. Skipping this can lead to undetected issues, such as improper filling placement or persistent discomfort.

Be Proactive
Commit to regular dental check-ups to maintain the longevity of your fillings and overall oral health.
Final Thoughts
Proper care after a dental filling is essential for its success and longevity. By avoiding these common pitfalls, you can ensure a smoother recovery, reduce the risk of complications, and enjoy the benefits of your restored tooth. If you experience any severe pain, loose fillings, or prolonged sensitivity, reach out to your dentist promptly for further guidance.
These tips serve not only to protect your new filling but also to contribute to a healthier and more confident smile.
