Many of you might not know, but there is a layer on your teeth called acquired pellicle. Its duty is to protect the sensitive dental areas. Professional teeth whitening treatments eliminate this layer, resulting in porous teeth. But how long are teeth porous after whitening?

It requires 24 hours to regenerate this protective layer. Therefore, the effectiveness of teeth whitening depends on the 48-hour post-procedure.

How Long Are Pores Open After Teeth Whitening?

The pores in your enamel open during the teeth whitening procedure. You can wait for 24-48 hours for them to close. Once they do, your teeth should feel less porous, and you can resume your routine habits.

Aftercare Post-48 Hours

Teeth whitening treatments use a bleaching agent to remove stains from your teeth. This agent penetrates your enamel through tiny pores, similar to how a hot washcloth opens pores on your face to clean it better.

For at least the first 48 hours after whitening, avoid dark-colored foods and drinks like berries, coffee, tea, red wine, and tomato sauce. Also, avoid acidic foods such as fermented items, vinegar, pickles, and citrus fruits.

Although the pores should return to normal size after 48 hours, you can be cautious for a full week to make the most out of your teeth whitening treatment.

Dental Care After Teeth Whitening

There are no major changes required in your dental care regimen. However, the following are a few extra tips to keep in mind:

  • Brush and Floss as Usual: Keep brushing twice a day and flossing once a day, just like you normally do.
  • Use Anti-Sensitivity Products: If your teeth feel sensitive after whitening, switch to anti-sensitivity toothpaste or use anti-sensitivity gel. Use the toothpaste as you normally would. Apply the gel to your teeth to help block the pores and reduce sensitivity.
  • Choose White Toothpaste and Clear Mouthwash: Avoid colored toothpaste and mouthwash, as they can stain your teeth.
  • Rinse with Water: If you eat or drink something that might stain your teeth, rinse your mouth with water to remove any leftover particles.
  • Wait 30 Minutes After Eating to Brush: After eating, especially acidic or sugary foods, wait 30 minutes before brushing or flossing. These foods can temporarily weaken your enamel, and brushing right away can damage it further.

How to Hydrate Teeth After Whitening?

The teeth whitening process can cause your teeth to lose moisture as the pores in your teeth open to let the whitening agents in, and fluids, and moisture can escape. The internal temperature of each tooth also rises during whitening, triggering further moisture loss.

  • After the procedure, your teeth will naturally rehydrate in two to seven days. However, you can accelerate this process:
  • Water hydrates your entire body, including your teeth. So, drink plenty of it.
  • Fluoride strengthens tooth enamel and promotes the remineralization of your teeth’s surface. Use an ADA-approved fluoride toothpaste.
  • Stop drinking soda and other carbonated drinks. They can cause more moisture loss and slow down the rehydration process.
  • Apply remineralizing gels to help restore lost minerals in your teeth.

Wrapping Up
