Is It Safe To Brush Teeth With Baking Soda Daily, With Braces, While Pregnant?

There are home remedies touted to help almost anything. Among these remedies found galore on the internet are those that simply don’t work at all, some that work for some people, and others that actually do work but pose cosmetic or health safety risk. This brings us to the question, is brushing teeth with baking soda safe?

According to Bhandal Dental Surgery, it is safe to brush your teeth with baking soda so long as it is “used correctly in order to protect the teeth’s enamel from damages. The soda should ideally not be used too frequently since it can damage the enamel as a result of frequent use. It should generally only be used about once per a week and for two minutes at a time”.

So, is it safe to use bicarbonate of soda for daily teeth cleaning, in other words replacing the regular toothpaste with it? NO.

Should You Clean Teeth with Bicarbonate Of Soda If You Have Braces?

According to Colgate, brushing with baking soda is not recommended for people with braces that contain orthodontic glue (your dentist will advise you accordingly) or permanent retainers. Baking soda can loosen the glue and cause these dental devices to fall, not to mention that the reaction involved can leave you with darker spots.

What about Brushing with Baking Soda While Pregnant?

Pregnancy is associated with lots of hormonal changes. These changes can according to Colgate increase the risk of dental problems including what the American Dental Association refers to as pregnancy gingivitis (swelling and bleeding of gums), periodontitis and loose teeth.

According to the American Congress of Obstetricians and Gynecologists (ACOG), pregnancy may also increase your risk of dental carries due factors such as increased mouth acidity, cravings for sugary substances, and reduced attention to oral care.

While brushing teeth during pregnancy is vital, it may not be sufficient. A dental appointment is also crucial, says Colgate. In addition to brushing and flossing your teeth regularly with normal toothpaste, it also helps to brush with baking soda every now and then. Baking soda helps to lower mouth acidity and hence reduce tooth corrosion and associated problems.

This is especially important for patients who experience “vomiting secondary to morning sickness, hyperemesis gravidarum, or gastric reflux during late pregnancy” as these factors increase exposure of teeth to gastric acid.

Brushing your teeth with baking soda aside, The American Congress of Obstetricians and Gynecologists recommends rinsing your mouth with a baking soda solution prepared by mixing 1 teaspoon of baking soda and 1 cup of water as a way to reduce the acidity in the mouth.

Is It Safe To Brush With Baking Soda And Lemon? And Strawberry?

You are likely to come across some websites and blogs suggesting the use of bicarbonate of soda and lemon for stronger teeth whitening effect. Bhandal Dental Surgery advises against this saying that the acidic nature of lemon can erode calcium from the teeth and thus wear them off. It can also cause gum inflammation.

Strawberries on the other hand can indeed help to whiten teeth naturally thanks to the vitamin C found abundantly in them but a baking soda and strawberry combo is not ideal for teeth, says the Bhandal Dental Surgery owing to the acidity in strawberries.

Why Brushing Teeth with Baking Soda Every Day is bad

With so many health benefits attributed to brushing with sodium bicarbonate, you may be tempted to use it as a daily replacement for your regular fluoride toothpaste. That is a bad idea. According to Bhandal Dental Surgery fluoride is crucial for strengthening of teeth enamel and should thus form part of your regular oral health care. As regards how you use the bicarbonate of soda for brushing, do it gently. Scrubbing the teeth or gums too hard or too long (longer than 2 minutes) is as bad as brushing too frequently or daily. It will erode the enamel; the protective hard surface of the teeth.

Brushing Teeth with Baking Soda and Salt

Some websites suggest using bicarbonate of soda alongside salt. The abrasive action of salt helps to add to the plaque fighting and teeth whitening effect of the bicarbonate. Sea salt is especially good since it is loaded with calcium, magnesium, iodine, and other nutrients.

Here is how to brush your teeth with baking soda and sea salt:

  1. Mix 3 teaspoons of sodium bicarbonate with 1 teaspoon of sea salt (or table salt)

Brushing Teeth with Baking Soda Side Effects and Risks

Brushing with sodium bicarbonate is not without its side effects and risks. Among the most significant side-effects and dangers of bicarbonate of soda teeth whitening and plaque removal are:

  • Enamel (and sometime dentine) damage if used inappropriately, for too long or too frequently.
  • Increased teeth sensitivity (to cold and hot drinks and foods).
  • Damage to dental braces and permanent retainers.

Mixing Baking Soda with Toothpaste

The fluoride in toothpaste forms an integral part of dental hygiene and health. You should thus only use baking soda alternately with toothpaste; Bhandal Dental Surgery specifically recommends using baking soda only one each week to avoid damage to teeth enamel and to capitalize on the teeth strengthening action of fluoride.

Rather than use baking soda alone, you may also want to use it alongside toothpaste. The first way to do that is to brush with baking soda first as explained above and then follow it up with your normal toothpaste. Alternatively, apply toothpaste to your toothbrush, then sprinkle some baking soda before brushing as usual.

You can also look for one of the many over-the-counter teeth whitening products with baking soda. If you decide to go that route, ensure that the product has the ADA Seal of Acceptance.
