Coffee is good at leaving evidence. So is red wine, tobacco products, dark foods, and simply getting older. Over time, enamel can pick up stains that make otherwise healthy teeth look dull or darker than you remember.
Professional teeth whitening offers a conservative way to brighten natural enamel without changing the shape or structure of your teeth. At the Henderson dental office of George Harouni, DDS, whitening begins with something more useful than choosing the lightest shade on a chart: understanding why your teeth changed color in the first place and what kind of result your enamel can realistically achieve.
Professional teeth whitening uses peroxide-based whitening gel to break apart stain-causing compounds within natural tooth structure. Dentist-supervised treatment can produce a more noticeable and predictable change than whitening toothpaste alone while allowing your teeth, gums, sensitivity, and existing dental work to be evaluated first.
Whitening works best when discoloration has developed within natural teeth or accumulated from everyday habits. Coffee, tea, red wine, tobacco, deeply pigmented foods, and natural changes in tooth color with age are common reasons patients seek professional whitening.
The important word is natural.
Crowns, veneers, fillings, bonding, and other tooth-colored dental work don't respond to whitening gel the way enamel does. If you have existing dental work in your smile line, Dr. Harouni evaluates its shade before treatment so that whitening your teeth doesn't leave an obvious color mismatch.
Some discoloration also responds less predictably than ordinary surface staining. A dental exam helps determine how much improvement is reasonable before you invest time or money in treatment.

There isn't one correct whitening method for every patient.
In-office teeth whitening is designed for patients who want a faster change. A professional-strength whitening treatment is carefully applied while the surrounding gums are protected. Depending on the treatment protocol and your starting shade, a noticeable improvement may be possible in one appointment.
This can be particularly useful before a wedding, reunion, photo session, or another special event when you don't want to spend several weeks using store-bought whitening strips.
Take-home teeth whitening takes a more gradual approach. Dentist-supervised whitening gel is used according to your treatment instructions over a series of applications. Results develop progressively, giving patients greater control over when to stop once they reach their desired shade.
During your appointment, Dr. Harouni can discuss which approach makes more sense for your smile goals, schedule, dental needs, and history of sensitivity.

Teeth whitening is generally considered safe when appropriate products are used correctly, although temporary tooth sensitivity and gum irritation are the most common side effects.
That matters if your teeth already react strongly to cold drinks or sweets.
Sensitivity can be influenced by the strength of the whitening gel, how long it remains in contact with the teeth, existing restorations, exposed root surfaces, gum recession, and your individual dental health. Rather than pushing through significant pain or discomfort for a whiter smile, Dr. Harouni can adjust the whitening plan around what your teeth tolerate.
Persistent sensitivity should also be evaluated before whitening. A painful tooth may need treatment rather than bleaching.
Many patients with healthy teeth and gums are good candidates, particularly when their main concern is yellowing or staining rather than tooth shape, spacing, or alignment.
Dr. Harouni will first look for issues that could change the treatment plan, including:
Sometimes professional whitening is enough. Sometimes it isn't.
If the concern involves a chipped tooth, an old crown, deep discoloration, worn enamel, or several cosmetic issues at once, Dr. Harouni can explain alternatives such as bonding, porcelain veneers, or a broader smile makeover instead of repeatedly whitening teeth that aren't likely to respond.
Professional whitening can make natural teeth several shades whiter, but the exact change isn't identical from patient to patient. Your starting shade, enamel, type of staining, whitening method, treatment time, and habits afterward all influence whitening results.
The goal isn't to chase an artificial white.
Dr. Harouni considers how the new shade works with the rest of your smile, including visible dental restorations and the natural variation between teeth. A believable result can still look significantly brighter without making every tooth appear flat or opaque.
Whitening also isn't permanent. Coffee, red wine, tobacco, and other staining habits gradually affect tooth color again. Good brushing, routine dental cleanings, and occasional whitening touch-ups can help maintain the result.
Whitening toothpaste may help control new surface stains between treatments, but it doesn't produce the same bleaching effect as peroxide-based professional whitening.

Teeth whitening cost reflects the whitening method selected, the amount of professional treatment required, and any dental care that needs to be completed before whitening begins.
Because whitening is generally considered an elective cosmetic procedure, dental insurance commonly does not cover the treatment. Our team can review your benefits and give you clear pricing before treatment begins.
For patients who prefer to spread out their cost, the practice offers flexible financing through Cherry, CareCredit®, and HFD.

Whitening looks simple until a patient has a crown that won't change color, sensitive enamel, uneven staining, or plans for additional cosmetic dental work.
That's where experience becomes useful.
Dr. George Harouni has practiced dentistry for more than 28 years, including more than two decades serving patients from the same Henderson location. He also teaches as a part-time instructor at the UNLV School of Dental Medicine. His approach to cosmetic dentistry starts by examining what is already there: your enamel, restorations, gum health, bite, tooth color, and the result you're trying to achieve.
Sometimes the right answer is professional whitening. Sometimes a less complicated treatment will do. In other cases, whitening becomes the first step in planning new bonding, veneers, or crowns so their final shade can be matched to the brighter natural teeth around them.
Our Henderson office also serves patients coming from Green Valley, Seven Hills, Las Vegas, and throughout the Las Vegas Valley.
If dull or stained teeth are the only thing you would change about your smile, you may not need an extensive cosmetic treatment plan.
Start with an evaluation.
Schedule an appointment with George Harouni, DDS to discuss professional teeth whitening in Henderson, Nevada, and find out which whitening option makes sense for your teeth.
There isn't a universal number. Many patients achieve a noticeable change of several shades, but whitening results depend on your original tooth color, enamel, type of stains, and treatment method. Dr. Harouni can give you a more realistic expectation after examining your teeth.
Professional whitening treatments typically use dentist-supervised products and treatment protocols that can produce faster results than many over-the-counter options. Store-bought whitening strips can lighten natural teeth, but treatment usually requires repeated applications and gives you less professional control over sensitivity, gum exposure, and shade planning.
Whitening toothpaste is better at removing or limiting certain surface stains than changing the underlying color of teeth. It can be useful for maintenance but shouldn't be expected to provide the same result as professional bleaching.
No. Crowns, veneers, fillings, implants, and other tooth-colored restorations do not bleach like natural enamel. If these restorations are visible when you smile, their color needs to be considered before whitening begins.
Yes, but schedule your appointment before the last minute. That gives Dr. Harouni time to examine your teeth, select an appropriate treatment, evaluate sensitivity, and allow the final shade to settle before the event.
