Quick summary of this article+
After a periodontal deep cleaning, home care decides whether the results last. In the first few days: don't chew on the treated side while the anesthesia wears off, eat soft foods at a mild temperature, keep hygiene gentle without skipping the area and use a toothpaste for sensitive teeth. It's normal to have sensitivity that fades, slight early bleeding and to notice gaps between your teeth — gaps that were already there, filled with tartar and swelling. In the long run: floss or use an interdental brush every day, control smoking and diabetes, go to your re-evaluation and keep up regular periodontal maintenance. Increasing pain, swelling, pus, fever, heavy bleeding or a tooth that moves call for contact. In Mooca, São Paulo, with Dr. Cléo Salustiano (CRO-SP 170844).
After a periodontal deep cleaning (scaling and root planing), what you do at home matters as much as what was done in the chair. The deep cleaning removes what had already built up. Your daily hygiene is what keeps it from building up again inside the freshly cleaned pockets — and that's what decides whether the results last.
In the first few days, the focus is recovery: gentle hygiene without skipping the area, soft foods and patience with sensitivity. After that, the focus shifts to maintenance, with no end date.
In this article, Dr. Cléo Salustiano (CRO-SP 170844) explains what to expect, what to do at each stage and which signs mean you should get in touch before your scheduled follow-up.

Step by step
- While the anesthesia wears off. Avoid chewing on the treated side and be careful with very hot drinks, so you don't bite your cheek or burn yourself without noticing.
- Eating in the first few days. Choose soft foods at a mild temperature and avoid chewing hard on the treated area.
- Keep up hygiene, gently. Soft-bristled brush and gentle strokes along the gumline. Don't skip the treated area — removing plaque is what calms the inflammation.
- Clean between your teeth every day. Floss or an interdental brush, as recommended for your case. That's where gum disease starts and where your toothbrush can't reach.
- Manage sensitivity. Use a toothpaste for sensitive teeth consistently and avoid very cold drinks in the first weeks.
- Follow prescriptions for the time directed. Mouthwashes and medications, when prescribed, are meant for a set period. Don't extend them on your own.
- Control your risk factors. Cutting back on or quitting smoking and managing diabetes, with medical follow-up, change how you respond to treatment.
- Go to your re-evaluation and maintenance visits. The re-evaluation measures what responded; regular maintenance is what keeps the disease stable over time.
What to expect in the first few days
While the anesthesia wears off, avoid chewing on the treated side. With the area numb, it's easy to bite your cheek or tongue without noticing. Be careful with very hot drinks during this time for the same reason.
It's common for your gums to feel sensitive, a bit sore to the touch and more reactive to cold. This discomfort is usually mild to moderate and eases day by day. Sensitivity to cold appears because, once the tartar covering part of the root is removed, that area is temporarily more exposed.
Slight bleeding when brushing in the first few days can happen and tends to decrease as the tissue heals. What's not expected is heavy bleeding that doesn't stop or that gets worse over the days.
Many people feel that their gums have "receded" and that gaps have appeared between their teeth, which can be bothersome. It's worth repeating: those gaps were already there, filled with tartar and swollen gum tissue. With the inflammation under control, the real situation becomes visible — it's an improvement, not a loss caused by the treatment.
In the first few days, choose softer foods at a mild temperature and avoid chewing hard on the treated area. Hard, crunchy, very hot, very cold or acidic foods tend to be more uncomfortable at this stage.
If you were prescribed a mouthwash, medication or specific instructions, follow them as directed and for as long as directed. Antiseptic mouthwashes, when prescribed, are meant for a set period — using them on your own, indefinitely, isn't the way to go.
| Sign | Expected or warning? | What to do |
|---|---|---|

How to keep the results in the long run
Keep brushing, including the treated area. Use a soft-bristled brush, gentle strokes and angle the brush toward the gumline — which is exactly where plaque builds up. Skipping the area is the most common mistake and the one that slows recovery the most.
Cleaning between your teeth is the key part. Daily flossing or an interdental brush, as recommended for your case, reaches where the toothbrush can't and where gum disease starts. If you have larger gaps after treatment, an interdental brush in the right size often helps.
Manage sensitivity without giving up on hygiene. A toothpaste for sensitive teeth, used consistently, reduces discomfort and lets you keep brushing properly. Avoiding very cold drinks in the first weeks also helps.
Control your risk factors. Cutting back on or quitting smoking improves healing, blood flow to the tissue and response to treatment — and it makes bleeding a reliable warning sign again, since smoking masks it. Managing diabetes, with medical follow-up, has a direct effect on your gums.
Go to your re-evaluation. It happens a few weeks later, with new probing compared to the initial mapping, and it shows which areas are under control and which still need attention. Skipping it means losing the yardstick for your treatment.
After that, regular periodontal maintenance is what keeps the disease stable. The interval depends on your case and is usually shorter than the routine check-up for someone who never had gum disease. Because the disease progresses without pain, having no symptoms doesn't mean everything is fine.
Get in touch before your follow-up if you notice severe or increasing pain, growing swelling, pus, a persistent bad taste, fever, heavy bleeding or a tooth that has started to move. These signs are outside the expected course and need to be checked.
What should I do in the first hours after a deep cleaning?
+
Avoid chewing on the treated side while the anesthesia wears off, so you don't bite your cheek or tongue without noticing, and be careful with very hot drinks for the same reason.
What can I eat after periodontal treatment?
+
In the first few days, softer foods at a mild temperature. Avoid hard, crunchy, very hot, very cold or acidic foods, and don't chew hard on the treated area.
Can I brush the treated area?
+
You should. Skipping the area is the most common mistake and the one that slows recovery the most. Use soft bristles, gentle strokes and angle the brush toward the gumline.
Do I need to floss right away?
+
Yes, as recommended for your case. Cleaning between your teeth is what keeps buildup out of the freshly cleaned pockets. If you're left with larger gaps, an interdental brush often helps.
Is bleeding normal after a deep cleaning?
+
Slight bleeding when brushing in the first few days can happen and tends to decrease as you heal. Heavy bleeding, bleeding that doesn't stop or that gets worse over the days is not expected.
How long does the sensitivity last?
+
It's usually mild to moderate and fades over the first few days. A toothpaste for sensitive teeth, used consistently, and avoiding very cold drinks help during this stage.
Why does it look like my gums have receded?
+
Because the swelling went down and the tartar filling the gaps was removed. The real situation became visible once the inflammation was under control — it's an improvement in health, not a loss caused by treatment.
Do I need an antiseptic mouthwash?
+
Only if it's prescribed, and for the time directed. Mouthwashes are meant for a set period, and using them on your own, indefinitely, isn't the way to go.
Does smoking after a deep cleaning get in the way?
+
A lot. Smoking impairs healing, reduces blood flow to the tissue and masks bleeding, which is the main sign used for follow-up. Cutting back or quitting noticeably improves your response.
When is the re-evaluation?
+
A few weeks later, with new probing compared to the initial mapping. It shows which areas are under control and which still need attention — skipping it means losing the yardstick for your treatment.
Will I need maintenance forever?
+
Gum disease is chronic, so the goal is ongoing control. Regular maintenance, at an interval set for your case, is what keeps things stable over time.
Which signs mean I should get in touch before my follow-up?
+
Severe or increasing pain, growing swelling, pus, a persistent bad taste, fever, heavy bleeding or a tooth that has started to move. These signs are outside the expected course.
If nothing hurts, can I space out my maintenance visits?
+
That isn't safe. Gum disease progresses without pain — having no symptoms doesn't mean it's stable. Probing at your maintenance visit is what tells you everything is fine.
Where can I get periodontal follow-up care in Mooca?
+
