Getting back to normal
You should not, and the reason is not just general health advice. The Academy of Periodontology says tobacco reduces the delivery of oxygen and nutrients to gum tissue, weakening the body's defences, which slows healing and makes periodontal treatment results less predictable. NIDCR calls smoking the most significant risk factor for gum disease and says tobacco use can delay healing and make treatment less successful. If you cannot quit outright, the days right after treatment are the highest value window to stay off it.
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.
Is this normal?
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.
Light bleeding after a deep cleaning is normal and expected. The ADA lists bleeding gums among the usual after effects of scaling and root planing, and Cleveland Clinic lists temporary bleeding as a known effect. Expect pink in your spit for the first few days, easing steadily. MedlinePlus states that after periodontal treatment, gum bleeding and tenderness should go away within three to four weeks. Bleeding that does not stop is a reason to call your dentist right away.
More questions
Usually yes, the gum tissue does not fill those gaps back in. Black triangles show up after a deep cleaning because hardened tartar and swollen gum tissue that filled the space between your teeth have been removed. Cleveland Clinic states that receding gums cannot grow back. Some of the gap can close slightly as swelling settles in the first weeks, but the underlying loss of gum height between the teeth is generally permanent. Cosmetic options exist through your dentist, including bonding and orthodontics.
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.
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.
Gum tissue that has already receded does not grow back after a deep cleaning. Cleveland Clinic states plainly that receding gums cannot grow back and that gum recession cannot be cured. What a deep cleaning does achieve is reattachment: the ADA describes root planing as smoothing the tooth roots to help the gums reattach to the teeth, which tightens the tissue and shrinks the pockets. Height that was lost stays lost, but the disease process driving further loss can be stopped.
Most practices schedule the re-evaluation about four to six weeks after scaling and root planing is finished, though your dentist sets the exact timing. The ADA says your dentist will schedule another visit to see how the gums have healed and to measure the depth of your pockets, and that if the pockets have gotten deeper, more treatment may be needed. That appointment decides whether you move onto a maintenance schedule or need further treatment on specific sites.
Teeth often feel looser right after a deep cleaning because hardened tartar that was wedged between and around them has been removed. That tartar was acting like a rough splint. Cleveland Clinic lists a loose teeth sensation among the possible effects of the procedure. For most people the feeling eases over the following weeks as inflamed gum tissue firms up around the roots. Looseness that gets worse over time, rather than better, reflects underlying bone loss and needs your dentist to assess it.
