Baking Soda and Peroxide on Teeth?
Baking soda and hydrogen peroxide can irritate gums and alter tooth surfaces when misused; concentration, frequency, and diagnosis matter.
The short answer
Using baking soda with hydrogen peroxide on teeth can cause abrasion, gum irritation, sensitivity, or chemical injury when the mixture, concentration, contact time, or frequency is unsuitable.
How do baking soda and peroxide affect tooth tissue?
Baking soda is a mildly abrasive alkaline powder, while hydrogen peroxide is an oxidising agent used in controlled whitening products. A homemade mixture does not provide a measured gel strength, tray fit, or protection for exposed root surfaces.
What should you do after considering this mixture?
Do not mix household products or scrub with the powder. Use fluoride toothpaste and a soft brush for routine cleaning, and ask a dentist about a tested whitening product after checking for decay, gum recession, and sensitivity.
When does a reaction to the mixture need care?
Arrange care for burning gums, white or peeling tissue, sharp sensitivity, pain, or changes after using the mixture. Rinse with water and obtain urgent advice after swallowing a significant amount or developing breathing or facial symptoms.
What should you ask about safer whitening options?
Ask whether whitening is appropriate for your enamel and restorations, which product and concentration are intended, and how to protect the gums. Ask what caused any existing stains before trying to remove them.
Frequently asked questions
Can baking soda whiten teeth?
It can help remove some surface stain through cleaning, but it does not correct every type of discoloration.
What if my gums turned white?
Rinse the area and stop the product; persistent whitening, pain, peeling, or ulceration needs dental assessment.
