Does bicarbonate of soda make teeth white
Bicarbonate of soda may remove some surface stain, but it does not bleach intrinsic tooth color or replace fluoride toothpaste.
The short answer
Bicarbonate of soda can help loosen some surface stain because it is a mild abrasive, but it does not bleach the internal color of a tooth and excessive scrubbing can wear surfaces. It also does not replace fluoride toothpaste or professional diagnosis of discoloration.
What causes surface stains on teeth?
Surface stains sit on enamel or in the acquired pellicle and may come from foods, drinks, tobacco, or plaque. Intrinsic discoloration lies within enamel or dentine and may follow development, trauma, medicines, aging, or pulp changes.
How can you reduce staining without scrubbing hard?
Use a soft brush and fluoride toothpaste with light pressure rather than repeatedly scrubbing with loose powder. A dentist can identify the stain type and discuss cleaning, whitening, restoration, or monitoring.
When should a dentist assess tooth discolouration?
Seek an examination for one darkening tooth, a new color change, sensitivity, pain, enamel defects, or discoloration that does not improve with routine cleaning. These features can point to a tooth problem rather than surface stain.
What could be causing the change in tooth colour?
Ask whether the color is external stain, fluorosis, enamel change, dentine color, decay, or a pulp problem. Ask which whitening or restorative option fits the tooth structure and your sensitivity risk.
Frequently asked questions
Can bicarbonate replace toothpaste?
It does not provide the complete formulation of fluoride toothpaste and should not replace routine fluoride brushing.
Why is one tooth turning dark?
A single dark tooth can reflect trauma, decay, or pulp change and should be examined.
