Teeth Whitening in Austin, TX

Although teeth whitening is generally safe, it may cause some teeth sensitivity and discomfort. Don't worry! This discomfort is only temporary, and it generally goes away on its own a few days after the procedure. 

That said, it doesn't mean you have to endure it. In this article, we will share a few tips that can help you reduce teeth sensitivity after teeth whitening. 


Not everyone experiences teeth sensitivity after a whitening treatment. Even in the case of those who do struggle with it, the level of discomfort can differ from person to person. That's because several factors can influence your teeth's sensitivity after the whitening treatment. 

  • The Frequency of the Treatment: Frequent whitening treatments may increase the chances of experiencing teeth sensitivity. It's generally recommended to have teeth whitening treatment once every 18 months. 
  • The Quality of the Treatment: At-home whitening kits are more likely to cause teeth sensitivity than professional treatments. That's because it's harder for people to apply the treatment correctly, and the bleaching agent can cause irritation if it comes in contact with your gums. 
  • The Treatment Itself: The bleaching agent in the whitening gels makes the enamel more absorptive, exposing the dentin. 


Teeth sensitivity can be frustrating, but there are ways you can reduce your discomfort: 

  • Use a Desensitizing Toothpaste: Start brushing your teeth with a desensitizing toothpaste about ten days before the whitening treatment. Leave the toothpaste on for a few minutes on your teeth before rinsing it with water. 
  • Use a Desensitizing Gel: Apply the gel before the treatment and leave it on for the recommended amount of time. 
  • Try a Different Whitening Treatment: Some whitening treatments can be more potent and cause more sensitivity. If you've noticed that your teeth are getting sensitive after using whitening trays, opt for a different type of treatment next time to give your teeth a break. 
  • Reduce the Frequency of Your Whitening Treatments: As mentioned, ideally you should whiten your teeth every 18 months or so. If you are unhappy with the appearance of your teeth sooner than this period, then you should try professional cleaning to remove some surface stains and brighten your smile. 
  • Avoid These Foods After Teeth Whitening: Stay away from cold, hot, and acidic foods and drinks in the hours and days following your teeth whitening treatment. 
  • Drink Through a Straw: If you prefer your coffee hot or want to enjoy a glass of cold soda, then it's best to sip them through a straw to minimize the contact with your teeth.
