What should I do in the first 48 hours after a deep cleaning?
Cited to 4 sources. Reviewed 2026-08-25.
Do not chew anything until the numbness is completely gone, which can take up to about seven hours. Then eat soft, lukewarm food, brush gently with a soft brush the same day, and clean between your teeth as usual but without force. Expect sore gums, light bleeding and cold sensitivity through day two. Take any medication exactly as prescribed. Cleveland Clinic says most people can return to their normal routines the same day, so this is about comfort more than restriction.
- No chewing until
- Numbness fully gone
- Numbness can last
- Up to about 7 hours
- Restart brushing
- Same day, gently
- Soreness peaks
- Day 2 to 3
What to expect, step by step
Lip, cheek and tongue numb on the treated side. Hard to speak clearly and to keep saliva in.
What to do: No chewing. Cool or lukewarm liquids and spoonable food only. Cleveland Clinic warns not to eat on the numb side because you can bite your cheek or gums without feeling it.
Feeling returns, replaced by a dull ache and tender gums. Pink saliva and a metallic taste are common.
What to do: Soft, lukewarm meal. Brush gently with a soft brush and floss without snapping. Warm salt water rinses for comfort. Take medication exactly as prescribed.
Soreness is at or near its peak. Cold drinks and cold air start to zing. Gums may look slightly puffy at the gumline.
What to do: Keep to soft food and room temperature drinks. Start a desensitizing toothpaste. Keep brushing and flossing gently, do not skip.
Ache is steady rather than worsening. Bleeding on brushing is lighter than day 1 for most people.
What to do: Stay off tobacco. Note anything that is getting worse rather than better, because that is the trigger to call your dentist.
The only hard rule: wait out the numbness
Scaling and root planing usually involves a local anesthetic, which the ADA notes may be required and Cleveland Clinic describes as applied before instrumenting below the gumline. Cleveland Clinic says local anesthetics can last from 30 minutes to 12 hours or more, and that after a dental procedure it may be difficult to speak clearly or eat for up to about seven hours.
Its specific warning is the one that matters here: avoid eating with the side of your mouth affected by the anesthetic, because you could bite the inside of your cheek or hurt your gums and not realize it. Cheek bites from eating while numb are the most common avoidable injury in the 48 hours after this procedure.
What to do, and what not to bother with
There is no wound to protect the way there is after an extraction, so most of the first two days is about staying comfortable while inflamed tissue calms down. Cleveland Clinic says most people can return to their normal routines the same day and that complications are rare.
The one thing that genuinely changes your outcome is keeping the freshly cleaned pockets clean. The ADA puts brushing twice daily with a soft brush and daily cleaning between the teeth at the centre of managing gum disease, and notes that cleaning between the teeth should not cause pain. Gentle and daily beats thorough and skipped.
- Do: wait for full sensation before chewing anything
- Do: brush gently with a soft brush the same day, angled 45 degrees to the gumline
- Do: keep cleaning between the teeth, sliding rather than snapping the floss
- Do: eat soft, lukewarm food and keep drinks at room temperature
- Do: take any medication exactly as your dentist prescribed
- Do not: smoke or vape, which the Academy of Periodontology says slows healing
- Do not: skip brushing the sore area, which is how a deep cleaning underperforms
- Do not: poke or wiggle teeth that feel loose
Normal at 48 hours
By the end of day two you should have sore, tender gums, some light bleeding when you brush, cold sensitivity, and possibly a feeling that your teeth are looser, longer or further apart. All of those appear in the standard lists. The ADA lists pain and swollen, tender or bleeding gums plus sensitivity for up to a week. Cleveland Clinic lists temporary bleeding, gum recession revealing tooth roots, a loose teeth sensation, sensitivity and soreness among possible effects, with tenderness lasting a couple of days.
What should not be happening at 48 hours is escalation. Cleveland Clinic names three reasons to contact your provider: bleeding that does not stop, pain that does not get better with medication, and severe swelling. If your day two is worse than your day one in those specific ways, call rather than wait for day three.
Call your dentist or oral surgeon if
- Bleeding that does not stop
- Pain that does not get better with the medication your dentist recommended
- Severe swelling of the gum, cheek or face
- Numbness that has not worn off by the next day
- Fever, pus, or a bad taste that keeps returning
- Pain that is clearly worse at 48 hours than it was at 24 hours
Related questions
Can I rinse with salt water after a deep cleaning?
Warm salt water rinses are a common comfort measure and are gentle on sore tissue. Follow any specific rinse instructions from your dentist first, particularly if medication was placed into a pocket, which the ADA notes can happen.
Do I need to take time off work?
Usually not. Cleveland Clinic says most people can return to their normal routines the same day. The practical limitation is the numbness, which makes eating and speaking awkward for several hours.
When can I use mouthwash again?
Ask your dentist. The Academy of Periodontology notes rinsing with mouthwash can help reduce plaque, but if a medicated agent was placed into a treated pocket you should follow the instructions that came with it rather than adding a product on your own.

Most people have sore gums and tender teeth for two to three days after a deep cleaning, with cold sensitivity that fades over the next one to two weeks. Cleveland Clinic notes that most people return to their normal routine the same day, though sensitivity can take a month or two to settle completely. Light bleeding when you brush is common early on and should ease as the gums heal. Your dentist will usually re-check and re-measure your gum pockets a few weeks later.
Wait until the local anesthetic has fully worn off before you chew anything. Cleveland Clinic notes dental numbness can last up to about seven hours and warns against eating on the numb side because you can bite your cheek or gums without feeling it. Once feeling returns, most people can eat normally the same day. Soft, lukewarm food is easier for the first two or three days while the gums are sore, and cold drinks may sting for a week or so.
Yes. Sore, tender, slightly swollen gums for a few days after a deep cleaning are expected. Cleveland Clinic describes tenderness lasting a couple of days, and the ADA lists pain and swollen, tender or bleeding gums among the normal after effects of scaling and root planing. Soreness should peak around day two or three and then improve steadily. Pain that is getting worse after day three, severe swelling, fever or pus is not part of normal recovery and should be checked.
Keep brushing twice a day and cleaning between your teeth once a day, starting the same day, just more gently than usual. Use a soft-bristled brush angled at 45 degrees to the gumline with short, tooth-wide strokes, which is the ADA technique. Slide floss in rather than snapping it, then curve it into a C shape against each tooth. Sore gums make people skip cleaning for a week, and that is the most common reason a deep cleaning underperforms.
