Does Teeth Whitening Help or Hurt Teeth?

side-by-side comparison of before and after teeth whitening

We all want sparkly, white teeth. It can make your smile go from ordinary to extraordinary! There are a lot of products today that claim to whiten your teeth. While most of them can do the job, at least temporarily, not all are a good option. It’s always a better option to talk to your dentist first before using an at-home teeth whitening procedure. Some options can cause damage to your teeth that is hard or impossible to reverse.

You may wonder, “Does teeth whitening help or hurt my teeth?” The answer isn’t quite as simple as a ‘yes’ or a ‘no.’ The dentists at Dental Partners of Boston can give you some insight that may help!

One of the most frequently asked questions our Boston dentists receive is: “Does teeth whitening damage your tooth enamel?” The simple answer, agreed upon by many dentists, is no. When performed correctly and under professional supervision, teeth whitening treatments do not harm your tooth enamel. Enamel is one of the hardest tissues in our bodies, designed to protect our teeth from daily wear and tear. During the whitening process, the gel penetrates the enamel and reaches the dentin, where it lightens the stained tissues. Always consult with your dentist to ensure the safest and most effective whitening treatment.

How Does It Work?

While whitening won’t damage the enamel, it can cause some tooth sensitivity. This sensitivity is often only temporary. As the whitening gel goes to work, the dentin tubules underneath the enamel can become exposed, leading to dehydration. However, the organic material found in saliva is quickly absorbed into the tubules, rehydrating the teeth. During this process, it is very important to avoid consuming any food or drink that contains color, as the teeth are more susceptible to staining until they are fully rehydrated. Additionally, it’s advisable to avoid hot or cold liquids during this time to prevent further sensitivity.

How Long Can Tooth Sensitivity Last?

Tooth sensitivity from teeth whitening is usually temporary and can last anywhere from a few hours to a few days. In most cases, sensitivity diminishes within 24 to 48 hours after the whitening procedure. The duration can vary depending on the individual’s oral health, the type of whitening treatment used, and the concentration of the whitening agent.

To minimize and manage sensitivity, you can:

  1. Use a desensitizing toothpaste: These toothpastes contain compounds that help block the transmission of sensation from the tooth surface to the nerve.
  2. Avoid extremely hot or cold foods and drinks: This can help prevent triggering sensitivity.
  3. Use fluoride treatments: These can help strengthen the enamel and reduce sensitivity.
  4. Take breaks between whitening sessions: If you’re using at-home whitening kits, giving your teeth a rest between treatments can help manage sensitivity, but it is best to see us about this procedure.
  5. Consult your dentist: One of our dentists can provide additional recommendations and may adjust the whitening treatment to minimize sensitivity.

If sensitivity persists for more than a few days or becomes severe, it’s important to consult with your dentist at Dental Partners of Boston.

Cautions During the Teeth Whitening Procedure

Disruption to the saliva flow can happen at times and cause dehydration. Simply breathing, smoking, specific medications, radiation treatments, and some medical conditions can cause dehydration. Dehydration can happen very quickly and rehydration can take several hours. Sensitivity occurs during the dehydration and rehydration process. If you experience this during the whitening process discontinue using the whitening gel or other product until the sensitivity is no longer an issue.

Teeth whitening can help improve the appearance of your teeth by making them look brighter and removing stains, but it does not improve the health of your teeth in a medical sense. Here are some ways teeth whitening can help and some limitations:

Benefits of Teeth Whitening:

  1. Aesthetic Improvement: Teeth whitening can significantly enhance your smile by removing stains and discoloration caused by foods, drinks, tobacco, and aging.
  2. Boosts Confidence: A whiter smile can increase self-esteem and confidence in social and professional settings.
  3. Non-Invasive: Whitening is a non-invasive cosmetic procedure that can achieve noticeable results without altering the structure of your teeth.

Limitations of Teeth Whitening:

  1. No Health Benefits: Whitening does not improve the health of your teeth or gums. It is purely a cosmetic procedure.
  2. Temporary Results: The effects of teeth whitening are not permanent and may require maintenance treatments to sustain the desired level of whiteness.
  3. Not Effective for All Stains: Whitening is most effective on extrinsic stains (surface stains) and less effective on intrinsic stains (stains within the tooth).
  4. Potential Sensitivity: Some people may experience temporary tooth sensitivity or gum irritation after whitening treatments.

Considerations:

  • Professional Supervision: Whitening treatments performed or supervised by a dentist are generally safer and more effective than over-the-counter products.
  • Healthy Oral Hygiene: Maintaining good oral hygiene practices, such as regular brushing, flossing, and dental check-ups, is essential for overall dental health and can help prolong the effects of whitening.

While teeth whitening can greatly enhance the appearance of your smile, it does not provide direct health benefits to your teeth or gums. The procedure also will not cause damage but can cause some sensitivity. It is important to combine whitening treatments with regular dental care for the best overall results.
