Luminous Results

Professional whitening, honestly assessed.

In-office treatment, custom take-home trays, or both — after a shade consultation that tells you what your teeth will actually do.

The short answer

Better Health Dental in Decatur offers in-office professional whitening and custom-fitted take-home trays with professional-strength gel. In-office treatment produces visible change in a single appointment; take-home trays work more gradually over one to two weeks and are easier to repeat later. Both begin with a shade consultation and a check that the discoloration is the kind whitening actually treats. Call (404) 446-2776 or book a consultation.

Whitening is the most requested cosmetic treatment in dentistry and the one most often oversold. Some stains lift dramatically. Some do not lift at all, because they are not stains — they are the color of the dentine underneath, or a filling, or tetracycline banding. Knowing which you have before you spend anything is the whole point of the consultation.

How does professional teeth whitening work?

Whitening gels use hydrogen peroxide or carbamide peroxide, which break down into small oxygen-containing molecules that pass through enamel into the dentine and chemically break apart the pigmented compounds trapped there. Nothing is scraped off and no enamel is removed. The difference between professional and over-the-counter whitening is concentration, contact, and supervision: a dentist can use a stronger gel safely because the gums are isolated, the trays are made to your teeth, and someone is checking.

That last point is why we start with an examination. Whitening gel in contact with an untreated cavity or exposed root surface is a bad experience, and whitening over active gum inflammation is worse.

Many patients do both: in-office to make the jump, then trays at home to hold it and touch up once or twice a year. If you have a date in mind, tell us what it is and we will work backward from it.

Why do teeth get darker in the first place?

  • Extrinsic staining — coffee, tea, red wine, dark sodas, curry, tobacco. Sits on and just within the outer enamel. Responds best to whitening.
  • Intrinsic discoloration — the dentine inside the tooth is naturally darker or has yellowed with age. Responds, but more slowly and to a limited degree.
  • Age-related thinning — enamel thins over decades and the darker dentine beneath shows through more. Partially responsive.
  • Tetracycline banding — gray or banded discoloration from antibiotic exposure during tooth development. Poorly responsive to whitening; usually a veneer discussion.
  • A single dark tooth — often a tooth that has had trauma or needs root canal treatment. External whitening will not fix this; it needs diagnosis first.

A single dark tooth is worth taking seriously rather than trying to bleach away. It frequently means the nerve has died, and that is a root canal question, not a cosmetic one.

Does whitening work on crowns, veneers, and fillings?

No. Porcelain and composite do not change color when whitening gel is applied to them. This matters in sequencing. If you have a tooth-colored filling or a crown in a visible position and you whiten your natural teeth around it, the restoration will stay as it was and may suddenly look too dark. The right order is to whiten first, let the shade stabilize for about two weeks, then match any new restoration to the new shade.

Patients who whiten after having a front crown made are the ones who end up disappointed, and the fix is replacing the crown. Tell us about any planned restorative work at the consultation so we can sequence it correctly.

How long do the results last?

Typically somewhere between six months and two years, with enormous variation driven almost entirely by diet and tobacco. A daily red wine or three-coffee-a-day habit will pull the shade back faster than anything else. The practical advantage of custom trays is that maintenance is cheap once you own them — a night or two of gel every few months holds the result indefinitely.

Nothing about whitening is permanent, and no honest practice will tell you otherwise. What it is, is repeatable.

Questions we are asked most.

Answers from Dr. Sharifa Walker, DDS. If yours is not here, call (404) 446-2776 and ask — the front desk will put the clinical questions in front of her.

How white will my teeth actually get?

That depends on what is causing the discoloration, and it is the first thing assessed at your consultation. Extrinsic staining from coffee, tea, wine, and tobacco often lifts several shades. Age-related yellowing responds more modestly. Gray tetracycline banding responds poorly. Rather than promise a number, Dr. Walker will show you your starting shade, say what range is realistic for your teeth specifically, and tell you if whitening is the wrong tool for what you have.

Does teeth whitening cause sensitivity?

Temporary sensitivity is the most common side effect and affects a substantial minority of patients. It typically appears during or shortly after treatment as a brief sharp sensation to cold or to nothing at all, and it resolves within a day or two. It is manageable: desensitizing toothpaste beforehand, fluoride application, shortening the daily wear time with trays, or spacing treatments further apart. Tell us if you already have sensitive teeth and we will plan for it from the start.

Is over-the-counter whitening worth trying first?

Whitening strips and toothpastes can help with mild surface staining and are inexpensive, so trying them is not unreasonable. Their limits are lower gel concentration, a generic fit that leaks onto the gums and misses the tooth margins, and no one checking whether whitening is the right treatment for your discoloration. If strips have not given you what you wanted, that is useful information to bring to a consultation rather than a reason to assume nothing will work.

Can I whiten while pregnant or breastfeeding?

Elective whitening is generally deferred during pregnancy and breastfeeding. There is no evidence of harm from peroxide whitening at dental concentrations, but there is also no body of research establishing safety in pregnancy, and the treatment is entirely elective, so the cautious course is to wait. Cleanings and necessary dental treatment during pregnancy are a different matter and should not be postponed — tell us if you are pregnant so care can be planned properly.

How much does professional whitening cost?

Cost depends on whether you choose in-office treatment, custom take-home trays, or both, and we quote it in writing at your consultation. Dental benefit plans classify whitening as cosmetic and generally do not cover it. Take-home trays are usually the better value over several years, because once the trays are made, maintenance costs only the gel. Financing through Sunbit and CareCredit is available — see financing.

What should I avoid after whitening?

For roughly the first 48 hours, teeth are more porous and more prone to picking up stain, so avoid coffee, tea, red wine, dark sodas, berries, tomato sauce, soy sauce, curry, and tobacco. After that, normal habits are fine — though the same list is what pulls the shade back over the following months. Drinking staining liquids through a straw and rinsing with water afterward measurably extends how long the result lasts.
