Teeth Whitening Facts & Myths

By Village Green Dental Care | May 25, 2026

Teeth whitening is a cosmetic dentistry treatment that aims to brighten and whiten a patient’s natural teeth shade.

There are a variety of professional methods that exist, as well as teeth whitening products you can use at home. To whiten your teeth effectively, some methods work better than others.

There has been a rise in the popularity of at-home teeth whitening kits, but it’s important to understand that these are not nearly as effective as in-office teeth whitening treatments done by dental professionals.

Professional Teeth Whitening Vs. DIY Whitening Kits

Professional Teeth Whitening

Professional teeth whitening is more effective and quicker than DIY whitening kits. The tooth whitening solutions that dentists use have higher concentrations of active ingredients.

DIY or home whitening kits are usually in the form of gel or paste. They only usually contain about 3% to 20% peroxide. As a result, you will need to use a kit almost every day for several weeks to see visible results. 

Teeth Whitening Facts & Myths

Misconceptions about teeth whitening exist so let’s review some of the most common myths and facts.

Myth – Teeth Whitening Makes Your Teeth Sensitive

This is one of the most common myths we encounter about teeth whitening. One of the side effects is tooth sensitivity and some gum irritation, however, it is not permanent. Our dentist will be able to minimize the effects or make them last for a shorter period of time. 

Fact – Teeth Whitening is Safe

Since people often experience tooth sensitivity or gum irritation, they feel that it is not safe. The truth is, teeth whitening is extremely safe. Especially when it is done by a professional. A dentist will never expose you to something that would cause harm to your teeth or oral health!

Myth – Teeth Whitening is Expensive

One of the reasons people tend to prefer at-home teeth whitening treatments is the cost. However, you have to consider the long-term cost of having to buy multiple whitening kits and the time you have to spend doing the treatment. At a dentist’s office, you will just have to sit through a one-hour session and you’ll have the results you want.

Fact – Dental Crowns & Veneers Cannot be Whitened

Teeth whitening treatments only respond to natural teeth. If you have a crown or veneers, you will end up with mismatched shades of teeth. If this is the case, your dentist will be able to discuss options with you so you can achieve the best results.

Staff are very welcoming, and answered my questions and made me feel comfortable. Day of surgery went smoothly and I am a very anxious person to begin with, but felt at ease knowing what to expect.
I am thankful for the care and support that was given to myself, and am looking forward to final results that will change my life for the better!
