Aftercare Guide
After Your Dental Filling
A filling is one of the quickest repairs in dentistry, and recovery is usually just a few hours of numbness and a few days of mild sensitivity. Here is what is normal, what helps, and what to call us about.

Understanding Your Recovery
A filling replaces the part of a tooth that decay or a small chip has damaged. At Innova Smiles we place tooth-colored composite fillings, which the American Dental Association describes as a mixture of resin and glass or quartz filler that provides good durability and resistance to fracture in small- to mid-size fillings. The material is hardened in the chair with a curing light, so it is fully set before you leave.
The first thing you will notice is numbness. The local anesthetic that kept you comfortable keeps your lip, cheek or tongue numb for a few hours afterward. The filling itself can take chewing right away; the reason we ask you to wait until the feeling returns is that a numb cheek or lip is easy to bite without noticing (Cleveland Clinic). If you must eat sooner, chew slowly on the other side.
Over the next few days, some sensitivity to cold, sweets or pressure is common, along with a little gum soreness where the tooth was isolated. The Cleveland Clinic describes these effects as temporary, usually settling within a week or two. Sensitivity that fades is normal; sensitivity that worsens, or a tooth that hurts sharply when you bite, is not, and both are easy to fix when you call early.
Long term, a filling needs the same care as the tooth around it: brushing twice a day with fluoride toothpaste, daily flossing and regular checkups. Decay can still start at the edge where the filling meets the tooth, which is why we check every filling at your visits. With that care, fillings last for many years; the Cleveland Clinic notes that, depending on the material, some last up to 20 years.
Your Filling Recovery Timeline
The First Few Hours
While You Are Numb
- Wait until the numbness has fully worn off before eating, usually within a few hours. A numb lip, cheek or tongue is easy to bite without noticing.
- Stick to cool or lukewarm drinks while numb; you cannot judge how hot something is.
- Children, and anyone who tends to chew on a numb lip, need a reminder not to bite or suck on the area.
- The filling is fully hardened, so it does not need protecting from normal use once feeling returns.
What to expect: A fat or tingling feeling in the lip and cheek on that side, and sometimes a strange feeling when you close your teeth together. Both fade as the anesthetic wears off.
Days 1–3
Settling In
- Brush and floss as usual, gently around the new filling.
- Expect some sensitivity to cold, sweets or pressure; avoid very hot or very cold foods for a few days if they bother you.
- Check your bite: your teeth should meet evenly. If the filled tooth touches first or feels 'high' when you close, call us for a short adjustment rather than waiting it out.
- Over-the-counter pain relief such as acetaminophen or ibuprofen, taken as the label directs, is enough for most people if they need anything at all.
What to expect: Mild sensitivity that comes and goes, and a tooth that feels slightly different to the tongue for a day or two. Both are normal and improve each day.
Weeks 1–2
Back to Normal
- Sensitivity should be fading. A desensitizing toothpaste helps if cold still bothers you.
- Eat normally; a hardened composite filling handles everyday chewing.
- If the tooth still aches, throbs, or hurts when you bite after two weeks, call us so we can check the bite and the tooth.
What to expect: Most people forget which tooth was filled within two weeks. Lingering or worsening symptoms are the exception and are worth a quick look.
Long-Term Care
Protecting the Filling
- Brush twice a day with fluoride toothpaste and floss daily; decay can still start where the filling meets the tooth.
- Avoid chewing ice, hard candy or pens, and never use your teeth to open packages.
- If you grind or clench your teeth, ask about a night guard; grinding wears and chips fillings.
- Keep your regular checkups so we can catch a worn or leaking filling before it becomes a bigger repair.
What to expect: A well-kept filling lasts for many years. We inspect every filling at your checkups and will tell you if one is wearing.
Do’s and Don’ts
Do
- Wait for the numbness to wear off before eating
- Brush and floss gently around the filling the same day
- Call us if your bite feels high or uneven after a day or two
- Use a desensitizing toothpaste if cold bothers you
- Take over-the-counter pain relief as the label directs if you need it
- Keep your regular six-month checkups
Don’t
- Do not chew while your lip, cheek or tongue is numb
- Do not drink very hot liquids until feeling returns
- Do not chew ice, hard candy or very sticky foods on the filled tooth in the first few days
- Do not ignore a tooth that hurts sharply when you bite; a small adjustment prevents a sore tooth
- Do not use your teeth as tools
Diet Guidance
While Numb
Safe to Eat
- Cool drinks
- Smooth foods you do not need to chew, such as yogurt or a smoothie, if you must eat
Avoid
- Anything that needs chewing
- Hot drinks and soups
- Chewing gum
First Few Days
Safe to Eat
- Your normal diet, starting with softer foods if the tooth is sensitive
- Lukewarm rather than very hot or very cold
Avoid
- Very hot or icy foods if they trigger sensitivity
- Hard candy, ice and very sticky sweets
After That
Safe to Eat
- Everything you normally eat
Avoid
- Chewing ice and using teeth to open things, which chip fillings and teeth alike
Pain Management
Most fillings need no pain medication. If the tooth or gum is sore, acetaminophen or ibuprofen taken as the label directs is usually enough
Sensitivity to cold and sweets is common for a few days and should fade within one to two weeks
A desensitizing toothpaste used twice a day eases lingering cold sensitivity
Sharp pain when biting usually means the filling sits slightly high; a short bite adjustment, not medication, is the fix
When to Contact Us
Contact us immediately if you experience
- Sharp pain when you bite that has not improved after two to three days
- Sensitivity that is getting worse instead of better, or a tooth that aches or throbs on its own
- Any sensitivity or ache still present after two weeks
- The filling feels rough, loose, cracked, or has fallen out
- Swelling of your gum, face or jaw
- Fever or chills
Emergency note: Fillings rarely cause emergencies. Call us right away for a swollen face or jaw, fever or chills, or severe pain that over-the-counter medication does not relieve. For swelling that affects your breathing or swallowing, go to the nearest emergency room.
