Blue Light Teeth Whitening

Does blue light teeth whitening damage teeth?

Blue light teeth whitening is a natural, effective, fast, and non-invasive method that does not harm the teeth. At Grenfell Dental, our treatment uses blue light to activate a unique natural whitening agent, delivering noticeable results in under an hour. The optimal whitening effect can last for over six months, depending on dietary habits. Compared to chemical whitening strips, blue light whitening is more natural, longer-lasting, and causes no damage to the teeth or enamel.

How long do the results last, and how often should I whiten?

The optimal results can last up to six months or more, depending significantly on your diet. Frequent consumption of coffee, tea, red wine, or chocolate may shorten the duration. It is generally recommended to undergo treatment 4 to 6 times per year. This frequency can help achieve a whitening effect of 3 to 5 shades by targeting both the outermost transparent enamel layer and the underlying yellowish dentin layer.

Will my teeth feel sore after the blue light whitening treatment?

Following blue light exposure, some individuals—particularly those with thinner enamel—may experience temporary tooth sensitivity or a dull ache, similar to the sensation from quickly consuming something very hot or cold. This is typically short-lived and causes no harm to the teeth. Prior to treatment, our dentists apply a protective barrier gel around your gums and lips to safeguard the soft tissues. Should you experience any discomfort post-treatment, you can request a special toothpaste from your dentist to help alleviate the sensitivity. In summary, blue light teeth whitening is a safe and effective procedure. However, if you have any specific concerns, please do discuss them with your dentist at Grenfell Dental.
