Brighten Up Your Smile: Is Teeth Whitening Permanent?

04/08/23 11 MIN Read

A bright, white smile is a sign of good health and hygiene. However, many people suffer from teeth discoloration, which can be caused by a variety of factors, including food and drinks, aging, and smoking. In this article, we will explore teeth whitening as a solution to teeth discoloration and answer the question: is teeth whitening permanent?

Different Methods for Whitening Teeth

Teeth whitening is a popular cosmetic dental treatment that can make a significant difference in the appearance of teeth. It’s normal for teeth to become discolored over time due to aging, food and drink stains, tobacco use, and poor oral hygiene. Fortunately, there are several methods available for teeth whitening that can effectively remove stains and restore a brighter, whiter smile.

In-office teeth whitening

In-office teeth whitening is a popular method that is done by a dental professional. This method involves applying a bleaching gel to the teeth and activating it with a special light. The procedure typically takes about an hour and can significantly whiten teeth in just one session.

Take-home teeth whitening kits

Take-home teeth whitening kits are also popular and can be provided by a dental professional. Most of the time, these kits come with a tray that fits your teeth and a whitening gel. The patient wears the tray with the gel for a specified amount of time each day until the desired level of whitening is achieved.

Over-the-counter teeth whitening products

Over-the-counter teeth whitening products are widely available and can include whitening toothpaste, whitening strips, and whitening gels. While these products can be effective to some degree, they typically take longer to achieve noticeable results and may not be as effective as professional teeth whitening methods. Some teeth whitening may even have side effect if not use with the right amount. 

Is Teeth Whitening Permanent?

Teeth whitening will not last forever. Over time, teeth may become discolored again due to aging and lifestyle factors. However, with proper maintenance, results can last for a significant amount of time.

The longevity of teeth whitening can vary depending on the individual and the method used. In general, professional teeth whitening methods tend to last longer than over-the-counter products. A meticulous oral care routine can help the results last from six months to two years.

How to Keep Your Teeth Whiter Longer?

Once you’ve achieved your desired level of teeth whitening, you’ll want to take steps to maintain your results for as long as possible. Here are some tips for keeping your teeth whiter longer:

Avoid staining foods and beverages

Foods and drinks that are high in color can stain teeth over time.  To maintain a brighter smile, try to avoid or limit foods and drinks like coffee, tea, red wine, berries, and tomato sauce.

Practice good oral hygiene

Brushing and flossing regularly can help remove surface stains and prevent new stains from forming. It’s also important to visit your dentist regularly for professional cleanings. Having a good oral care routine can help you save money and pain further down the track. So don’t underestimate the importance of regular dental visits for a professional clean, book your appointment today.

Drink with a straw

Drinking through a straw can help minimize contact between staining liquids and your teeth.

Consider touch-up treatments

Over time, teeth may become discolored again even with proper maintenance. Consider touch-up treatments to maintain your results, such as using an at-home whitening kit or scheduling periodic in-office whitening treatments.
