Teeth Whitening treatment at Abul Makarem Dental Clinic

Want a brighter smile? You have two options: whitening in our office, or an at-home kit. Both use a peroxide-based bleaching gel. At-home kits use a lower-strength gel (3–20% peroxide); in-office whitening uses a stronger gel (15–43% peroxide), applied under our supervision.

In general, more time with a stronger gel means whiter teeth — but a stronger gel needs less time on the teeth, not more. Leaving a strong gel on too long dries out the tooth and makes it more sensitive.

Each option has trade-offs. Talk to us before trying an at-home kit. One thing to know either way: bleaching doesn’t work on porcelain crowns or composite fillings — it only whitens natural tooth enamel.

In-office whitening works faster because the gel is stronger, and we can use heat, light, or both to speed up and boost the result.

Most patients see noticeable results — typically three to eight shades brighter — after a single ~45-minute in-office visit.

Whitening can leave teeth temporarily sensitive, and it can be uncomfortable if your teeth are already sensitive. Used incorrectly, at-home kits can also burn or temporarily bleach the gums — one more reason to check with us before you start one.

Is Teeth Whitening Permanent?

Whitening works best on teeth that are more yellow, less well on teeth that are more brown, and it likely won’t work at all on teeth that are gray or purple.

Whitening fades over time — anywhere from a few months to about three years, depending on the person. It fades faster if you smoke or drink things that stain teeth, like coffee, tea, or dark sodas.

Frequently Asked Questions

What are my options for whitening my teeth?

Two: whitening in our office, or an at-home kit. Both use a peroxide-based bleaching gel — at-home kits use a lower-strength gel (3–20% peroxide), in-office whitening uses a stronger one (15–43% peroxide) applied under our supervision.

How long does in-office whitening take?

Most patients see noticeable results after a single ~45-minute visit. We can use heat, light, or both to speed up and boost the result.

How much whiter will my teeth get?

Typically three to eight shades brighter, though results vary by person and by how yellow versus brown, gray, or purple your teeth are to start with.

Does whitening hurt?

It can leave teeth temporarily sensitive, and it can be uncomfortable if your teeth are already sensitive. Leaving a strong gel on too long dries out the tooth and increases sensitivity, which is why in-office sessions are supervised and timed carefully.

Will whitening work on my crowns or fillings?

No — bleaching only whitens natural tooth enamel. It doesn't work on porcelain crowns or composite fillings, so an already-crowned or filled tooth won't lighten the same way the teeth around it do.

How long do results last?

Anywhere from a few months to about three years, depending on the person. It fades faster if you smoke or drink things that stain teeth, like coffee, tea, or dark sodas.

Is whitening right for everyone?

It works best on teeth that are more yellow, less well on teeth that are more brown, and it likely won't work at all on teeth that are gray or purple. We can tell you what to realistically expect at a visit.

Is an at-home kit safe to use without seeing you first?

Talk to us before trying one. Used incorrectly, at-home kits can burn or temporarily bleach the gums, which is one reason we recommend checking with us before you start.

In-office or at-home — which should I choose?

In-office whitening works faster because the gel is stronger and we can boost it with heat or light. An at-home kit is a slower, lower-strength option. Talk to us about which fits your teeth and your timeline.

How much does in-office whitening cost?

A firm figure is confirmed after the dentist checks your teeth and gums. Whitening treatment varies with the degree and cause of staining, the materials and technique suitable for your teeth, whether any dental work is needed first, the complexity of reaching an even result, and the number of visits. The consultation gives you a suitable plan and its confirmed total.
