Can you use bicarbonate of soda on your teeth
Bicarbonate of soda can polish some surface stain, but loose powder is not a substitute for fluoride toothpaste or dental care.
The short answer
Bicarbonate of soda can remove some surface stain through mild polishing, but brushing with loose powder does not provide the complete fluoride protection of toothpaste and should not replace routine care.
What is sodium bicarbonate used for in toothpaste?
Sodium bicarbonate is a soluble alkaline powder used in some formulated toothpastes. Its cleaning effect comes mainly from physical disruption of deposits and stain, while fluoride toothpaste supports enamel remineralisation and cavity prevention.
How can you clean your teeth gently and protect enamel?
Use a fluoride toothpaste made for brushing and a soft brush, with gentle pressure around the gumline. If you choose a bicarbonate-containing toothpaste, use the finished product as directed rather than mixing powders with acids or abrasive ingredients.
When should stains or sensitivity be checked by a dentist?
Seek care for persistent stains, sensitivity, bleeding, rough enamel, or pain because these can reflect decay, erosion, recession, or gum disease. A dental cleaning removes hardened calculus that home powders cannot safely remove.
What should you ask about the cause of tooth discolouration?
Ask whether the discolouration is stain, calculus, or a change inside the tooth, and whether your brushing is causing abrasion. Ask which fluoride toothpaste and cleaning method suit your enamel and gums.
Frequently asked questions
Does bicarbonate remove tartar?
No. Tartar is hardened mineralised calculus and needs professional instruments for removal.
Can bicarbonate whiten a yellow tooth?
It may affect surface stain, but a yellow colour within dentine needs assessment before whitening is chosen.
