Brushing Teeth with Baking Soda -Does Baking Soda Whiten Teeth?

What causes teeth discoloration?

Of course you want to whiten your teeth with baking soda because you do not like their current color. In short your teeth are discolored or something close to that. There are plenty of individuals who are suffering from teeth discoloration. Before getting down to the role of baking soda let’s see the causes of teeth staining.

Teeth may get discolored by stains that occur on the surface of inside of the tooth and this may occur as;

  • Extrinsic – mostly causes by coffee, soda and wine among other food and drinks that may cause staining. This is alongside habits like smoking
  • Intrinsic – discolors the tooth from the inner layers, from the dentine. This layer may darken and exhibit a yellow color. Among the causative agents include too much fluoride during childhood when teeth are growing and developing. When mothers in their second trimester take tetracycline antibiotics or administer them when you are 7 years younger, teeth discoloration may occur. Other forms of discoloration occur due to internal bleeding of a permanent tooth and genetic predisposition.
  • Senile – with age the dentine yellows with time as the enamel gets thinner. This may be caused by reduced care of the teeth hygiene by the old. Also due to slow replacement of the white part, the dentine.

These three causative agents of teeth discoloration clearly show that one medication may work best for one while show no efficacy in another.

Everybody desires white teeth. Anybody would be willing to do anything to have it white. This includes ripping the benefits of some chemicals at times at the expense of the teeth themselves.

Such includes sodium bicarbonate being used as a teeth whitener.

Baking soda and teeth whitening

Sodium bicarbonate or commonly baking soda has been used in toothpaste formulations for a long time for its abrasive nature. For firms that prepare this chemical such as renowned Arm and Hammer Baking Soda Company skewed the market to their side of the court by stating its medicinal significance. Companies that have prepared their toothpaste with plain sodium bicarbonate include Church and Dwight. Colgate-Palmolive and Unilever have this beneficial ingredient in their Colgate and Close-up formulations respectively. So it really does work. Just how does it do it?

Sodium Bicarbonate;

  1. Changes pH of the oral cavity – a healthy mouth is non-acidic, neutral or alkaline. A pH of 7.0 or above is desirable. At pH lower that 7.0, the tooth roots begin to dissolve. The enamel may get eroded and tooth discoloration and cavitation occurs with lower pH. Sodium bicarbonate having a pH of 8.4 helps neutralize the acidic environment created by bacterially broken down sucrose. It further alkalinizes the oral cavity, promotes re-mineralization. It removes the layer of bacteria (plaque) that is responsible for the discoloration of the teeth.
  2. Is a polishing agent – due to the abrasive nature of sodium bicarbonate, plaque layered on the enamel of teeth are scrubbed off. With reference to the relative dentin abrasion tests done on straight sodium bicarbonate, its abrasiveness is favorable with low abrasivity to the overall state of the enamel. This is as compared to other oral formulations, dentifrices and brands. Sodium bicarbonate, therefore, when used in the correct amount, is an effective polishing agent.
  3. Increases calcium uptake by the enamel – calcium is important in the development of the teeth which is a calcified tissue. This may help in the strengthening of the enamel and the dentine layer not therefore exposed to cause yellowing.
  4. Augments anticaries agents – sodium with the buffer effect on the oral cavity prevents further destruction of the enamel and the dentine that causes browning and even darkening of the teeth (cavitation).

What do studies and online forums like Yahoo answers say about Sodium Bicarbonate’s effectiveness in whitening teeth?

Your teeth draw much emphasis on the aesthetics most essentially the envied snow-white color. White lustrous teeth undoubtedly are a considerable factor in portraying our confidence. Therefore, various researches have been conducted to test for the effectiveness of sodium bicarbonate as a potential whitener;

  1. A laboratory study compared the whitening effect of brushing the teeth with sodium bicarbonate-based dentifrices and standard dentifrices. The latter did not have any sodium bicarbonate. At the end of the experiment, all the sodium bicarbonate-based dentifrices were effective in the removal of yellow intrinsic tooth stain. (J Clin Dent.1998;9(3):72-5)
  2. In a double-blind comparison of two equivalent groups of subjects, parallel, received in random, a Test (sodium bicarbonate-based) or Control dentifrices. They were instructed to brush twice daily with the dentifrice given and avoid any other. After a 6 week period, the group of subjects using the Test showed remarkable improvement in the whitening of their teeth. The Control group did not show significant whitening. J Clin Dent.2004;15(3):71-5
  3. Online forums have indicated vast knowledge on the efficacy of bicarbonate in whitening of the teeth. Such forums include Yahoo Answers. According to most yahoo users, baking soda works great for teeth whitening at home.
  4. According to NIH, Sodium bicarbonate in dual phases of other dentifrices such as calcium and phosphate has shown improved efficacy in removal of extrinsic tooth stain compared to hydrated silica dentifrices.

Why use Baking Soda Teeth Whitening? Is it better Compared to other Teeth whitening methods?

Since not all toothpastes are equal, some are highly abrasive and even scrub off the tooth enamel. According to the Relative Dentin Abrasivity (RDA) table, sodium bicarbonate has an index of 7 which is very low. This shows that relative to some toothpastes like Colgate herbal with an index of 110, sodium bicarbonate is less abrasive to the dentine. Toothpastes with lower abrasive ratings are recommended.

Baking powder is fast acting within 30 minutes making it very effective. It is also the cheapest alternative to whiteners such as bleaching gels which are more expensive.
