Teeth whitening is one of the most popular cosmetic dental procedures, offering your patients a whiter, more youthful smile. Whether you’re looking to whiten your teeth for a special occasion in Charlotte or simply improve the aesthetic of your smile, this treatment can deliver both rapid and dramatic results. One common question, however, is how long it will take after the process for the patient to notice differences in their teeth.

We provide both in-office professional teeth whitening treatments and take-home whitening kits. Let’s learn how long it takes to see results from the treatment, which factors influence the speed of whitening, and how to maintain a bright smile.

In-Office Teeth Whitening: Instant Results

If you are seeking fast, noticeable results, in-office teeth whitening is the way to go. Typically, in-office teeth whitening uses a stronger gel and is often combined with a special light to activate it. It can yield fast, outstanding results in just one hour, and the patient can observe the difference immediately after the procedure.

After the process, you can expect your teeth to whiten several shades, and they will continue to get whiter in the next 24 hours. The effects can vary from several months to a year, depending on your oral care practices. In the Charlotte area, people enjoy local restaurants or coffee shops. You need to be mindful of your oral care habits, including those around coffee or red wine.

Factors That Affect Teeth Whitening Results

Although in-office teeth whitening procedures can immediately provide a whiter smile, the speed at which they can be completed depends on several factors. Understanding those factors can help you establish the right expectations for the outcome.

1. Initial Teeth Color

If your teeth are substantially stained or discolored, you may see results more easily and immediately. Slightly stained teeth that are yellow will whiten faster than teeth that are stained from smoking or from drinks like coffee or tea because of how saturated they are with darker colors. 

Coffee culture is dominant in Charlotte, and you might find that your teeth benefit even more from whitening after regularly drinking coffee. For deep stains, additional procedures might be needed to whiten your teeth.

2. Type of Whitening Treatment

Depending on the type of whitening procedure that you use, the outcomes that you can expect can vary significantly. In-office whitening would work the fastest, whereas a home whitening kit would take a few days or a few weeks at most to notice the first noticeable difference. A home kit would work at a slower pace since it is less potent.

If you want instant results, in-office whitening is the best choice, while take-home products are best for those seeking gradual progress.

3. Condition of Your Teeth

The treatments work faster and more effectively when teeth are healthy, free of cavities or other oral health issues. If a person has gum disease, cavities, or enamel wear, their dentist may suggest treating these conditions first to ensure a safe and effective whitening process. A pre-whitening checkup with your dentist can help ensure the treatment works to its best potential.

How to Maintain Results and Prolong Whitening

Even though you might notice immediate results from an in-office whitening procedure, maintaining them takes some effort. If you want to know how long we can keep teeth whitening results, here are some tips to keep your results lasting for an extended period of time:

1. Avoid Staining Foods and Drinks

In the days following the completion of the treatment, you must steer clear of any foods and beverages that could cause staining of the teeth, including coffee, tea, red wines, berries, and dark sauces. These substances are best avoided in the first 48 hours after the teeth-whitening procedure, as the teeth are now more porous and thus more susceptible to staining. 

As a resident of Charlotte, where coffee shops are common in many neighborhoods, you should cut down on your coffee consumption and drink through a straw to minimize exposure to your teeth.

2. Practice Good Oral Hygiene

Regularly brushing and flossing your teeth is essential for removing plaque and food particles that may cause discoloration. You should use a whitening toothpaste to maintain your white teeth. In addition, it is advisable to use a non-irritating mouthwash to keep your teeth white.

3. Regular Touch-Ups with Take-Home Kits

For long-lasting results, you can always use our take-home whitening kit. The kit helps you to retain your bright smile and can be used from time to time to prevent stains.

Achieve Brighter Teeth in No Time

If you want a brighter smile, whitening procedures can deliver dramatic results in a very short time, especially with in-office procedures. You can see a brighter smile in an hour with in-office whitening, but take-home kits may give you gradual results. The time it takes for your teeth to whiten varies depending on your initial tooth color, the treatment you choose, and your current oral health.

If you’re looking for teeth whitening in Charlotte, Dentistry of Uptown Charlotte is determined to help you achieve the smile you’ve always dreamed of. With teeth whitening, you can choose a quick, noticeable improvement for a special occasion or opt for a lasting result using our take-home kits.

FAQs

How long does it take to see results after in-office teeth whitening?

Results can be observed immediately following an in-office teeth whitening treatment. Within an hour, patients can notice their teeth have brightened by several shades, and this effect will continue to improve over the next 24 hours.

Can I drink coffee after teeth whitening?

In the first 24-48 hours after whitening, avoid drinking coffee, tea, or other drinks that may stain your teeth. This is the most vulnerable period for tooth staining, during which the whitening process may be less effective.

How long do the results of teeth whitening last?

The effect of teeth whitening may last for several months to a year. However, this may depend on your eating habits, oral hygiene, and whether you continue to avoid staining foods and drinks.

How often can I get my teeth whitened?

An in-office teeth whitening procedure can be done periodically, every 6 to 12 months, as needed. For take-home kits, you can maintain a bright white smile by touching up as needed. Just consult your dentist on how to do it.

Will teeth whitening work for everyone?

Teeth whitening can be effective in most cases, but it may not be possible in all cases of discoloration. Whiteners can be effective for yellow discoloration but may be less effective for brown or gray discoloration caused by medicines or trauma.
