Is oxygen teeth whitening safe for children?
✅ Safe for children over 12 years old under a dentist’s supervision using a low concentration of hydrogen peroxide.
❌ Not recommended for younger children, as their enamel is still weak and sensitive.
Is oxygen teeth whitening painful?
The procedure is not painful at all, but you may feel slight temporary sensitivity after the session, which usually disappears within about two days.
How long do the results of oxygen whitening last?
⏳ Results last from 6 months up to a year, depending on daily care and diet (coffee, tea, soft drinks).
Can I do oxygen whitening at home?
It’s possible, but only with dentist-approved products.
⚠️ Using high concentrations without supervision can cause enamel erosion or gum irritation.
Does oxygen whitening damage the enamel?
❌ No, if done correctly under dentist supervision, it does not harm the enamel.
✅ In fact, it helps remove surface stains and preserves the natural tooth color.
How many sessions are needed to see results?
⏱️ In most cases, results appear after the first session, but some people may need two or three sessions depending on the degree of discoloration.
Can pregnant or breastfeeding women undergo oxygen whitening?
❌ Not recommended during pregnancy or breastfeeding, as there isn’t enough research on its effects on the baby or milk.
Can children with baby teeth undergo whitening?
❌ Absolutely not. Baby teeth are very sensitive, and their enamel is weak, so even low concentrations of oxygen can cause damage.
Is there a difference between oxygen whitening for children and adults?
✅ Yes, the difference is in the concentration of the whitening agent and the session duration.

Children: lower concentration and shorter sessions.
Adults: higher concentration and longer sessions for a clearer result.

Is scaling (cleaning) necessary before oxygen whitening?
✅ Yes. Whitening is more effective when teeth are free of tartar and plaque. Scaling allows the whitening agent to reach every surface for better results.
Is oxygen whitening suitable for all types of teeth?
❌ No, not for everyone. People with cavities, enamel erosion, or old fillings should treat these issues first before whitening.
Is there a difference between in-office whitening and at-home whitening?
✅ Yes. In-office whitening is stronger and faster because the dentist uses higher concentrations under careful supervision.
At-home whitening is gentler and slower but safe and suitable for adults who want to start gradually.
Can teeth whitening lighten very dark yellow teeth?
✅ It helps lighten the shade, but results depend on the type of discoloration.
❗ If discoloration is caused by medication or enamel problems, additional treatments like veneers or laser whitening may be needed.

Are there foods or drinks to avoid after whitening?
⚠️ Yes, for 48 hours after the session, avoid:

Coffee, tea, cola
Curry, colored sauces
Smoking
Because teeth are sensitive and prone to staining during this period.

Can I whiten my teeth while wearing braces?
❌ No, it’s not suitable during orthodontic treatment.
✅ It’s better to wait until after removal, as the whitening agent cannot reach surfaces under the wires or brackets.
Does oxygen whitening affect the gums?
✅ If done correctly, it does not harm the gums.
❗ But if the whitening gel stays in contact with the gums for too long, it may cause slight redness or irritation, which usually disappears within two days.
Can I repeat whitening every month?
❌ No, that’s too frequent for your teeth.
✅ It’s best to repeat whitening every 6 months to a year to keep enamel strong and maintain the natural tooth color.
