After years of coffee and tea drinking, maybe smoking cigarettes, cigars and chewing tobacco or even taking antibiotics, your once nice white teeth are starting to look a bit discolored…No matter how old a person is, perfect pearly white teeth are a must in the age of social media and selfies, but what is the “real cost” of these teeth whitening treatments? This is a very important question to ask…
Like many common dental procedures and materials that are available, most consumers are not thinking about the toxicity of the treatment, the damage that is done to the teeth, or even the dangers of the materials being used. Especially since you may use the same product for a long period of time. You simply go to the store and look for the tooth treatment that boldly claims if you use this product you will have a “whiter-brighter” smile!
Even though tooth enamel is the hardest substance in the body, it is also porous, which means it can be affected by what we eat and drink, especially eating acidic foods and drinking carbonated beverages and fruit juices. Unfortunately, our enamel cannot regenerate itself. This is why in theory, teeth whiteners may sound great, but in reality, these products can actually be toxic because they can infiltrate the enamel. Other problems that can occur from teeth whiteners are tooth sensitivity, toxicity to cells (cytotoxicity), and gum (gingival) irritation.
A recent study looked at the biocompatibility and abrasiveness of various whitening and conventional toothpastes. The ingredients included:
- Carbamide peroxide – can cause stomach upset, an episode of vomiting or throat irritation if swallowed
- Hydrogen peroxide – can damage enamel if used in high concentrations for long periods of time – can burn gums, tongue, and roof of the mouth
- Sodium lauryl sulfate (the most toxic agent used as a detergent)- significant toxic effects in vitro
- Hydrated silica – may be toxic to the liver
- Aluminum oxide – may cause oxidative stress and cell death in liver and kidney tissues
- Sodium monofluorophosphate – can be cytotoxic – can cause enamel defects
- Sodium benzoate- a chemical preservative may cause kidney and liver injury
- Assorted preservatives, colors, flavors, essences, and buffering agents were found.
In this study, they used human gingival fibroblasts with assorted dilutions that were exposed to various toothpaste to determine cytotoxicity and genotoxicity. They found some of the whitening toothpaste was significantly cytotoxic, while some of the conventional toothpaste caused significant enamel changes. What can also become a problem with these ingredients is that they can become more toxic when combined with each other.
Thankfully there are other options such as using natural teeth whitening alternatives which should lighten the natural color of teeth without eroding the dental surfaces. Some safer – milder natural teeth-whiteners that also contain organic acids include:
- Lemons
- Limes
- Apples
- Grapes
- Cherries
- Strawberries
- Oranges
- Papaya
- Pineapple
- Banana peel
These various natural components/compounds have been found to whiten teeth naturally:
- Limonene found in citrus fruit peel essential oil
- L-ascorbic acid (vitamin C).
- Citric acid
- Malic acid
- Phthalimido peroxy caproic acid found in Vanilla Fruits
- Bromelain and Papain – found in papaya and pineapple
- Aloe Vera juice
- Sodium bicarbonate
The takeaway is that while there are many over-the-counter products that exist to whiten teeth, they may wind up doing more harm than good over time. Using natural remedies is always going to be a better choice, especially when it comes to your oral health!
