How whitening strips can damage your teeth

by

Our results showed that treatment with hydrogen peroxide similar to those found in whitening strips is enough to make the original collagen protein disappear, which is presumably due to the formation of many smaller fragments.

The team is not yet sure whether this damage is permanent or if there is any way of reversing it. In the future, the researchers also plan to find out whether hydrogen peroxide affects not just collagen, but also other proteins that dentin contains.

Understanding the Risks of Whitening Strips on Tooth Collagen

Whitening strips have become a popular at-home teeth whitening solution for many individuals. However, recent studies have raised concerns about the potential damage these strips can cause to tooth collagen. The use of hydrogen peroxide in whitening strips has been linked to the degradation of collagen proteins, which are essential for maintaining healthy teeth and gums.

The Science Behind Whitening Strip Damage

When hydrogen peroxide is applied to teeth using a whitening strip, it breaks down into smaller fragments that can penetrate the tooth enamel. These fragments then interact with the collagen protein, causing it to break down over time. This process can lead to the formation of smaller collagen fragments, which can accumulate and cause damage to the surrounding tissue. As a result, the teeth may become more sensitive, and the gums may become inflamed.

Long-Term Effects and Reversibility

The long-term effects of whitening strip use on tooth collagen are still not fully understood. However, it is believed that repeated exposure to hydrogen peroxide can lead to permanent damage. In some cases, the damage may be reversible, but this requires further research to confirm. It is essential for individuals considering using whitening strips to take necessary precautions and follow the instructions carefully.

Health benefits of baking soda and lemon juice

by

Several scientific studies have examined the health benefits of baking soda and lemon juice separately, but there is not much research to support the combined effects of these two ingredients.

This article discusses some of the potential health benefits of consuming baking soda and lemon juice mixtures.

A note about pH

The idea of combining baking soda and lemon juice draws on basic principles of acidity and the pH scale.

Scientists use the pH scale to measure the acidity of a solution. A solution can have a pH level between 0 and 14.

The lower the pH, the more acidic the solution, so:

  • pH levels below 7 indicate an acidic solution
  • pH levels above 7 indicate an alkaline, or base solution
  • neutral solutions, such as pure water, have a pH of 7

Baking soda, also known as sodium bicarbonate, is a base. This means that when people dissolve baking soda in water, it forms an alkaline solution. For example, a 0.1 molar solution of baking soda has a pH of around 8.3.

Lemon juice contains citric acid and has a pH of around 3. Adding baking soda to lemon juice will raise the pH to produce a more neutral solution.

Skin care

Usually, the skin has a weakly acidic pH of about 5.7. Bases, such as baking soda, will increase the pH of the skin. Higher pH levels can disrupt the barrier function of the skin, which may lead to dryness, excess oil production, and acne.

Lemon juice appears to have obvious skincare applications because it contains concentrations of vitamin C and citric acid, which both provide powerful skin benefits. Citric acid is an alpha-hydroxy acid (AHA) that manufacturers commonly use in chemical peels.

However, skin cells naturally repel water-soluble molecules, such as vitamin C. This means that very little vitamin C will actually penetrate the skin.

The high acid content of lemon juice can lower the pH level of the skin. Low pH levels may cause skin irritation, hyperpigmentation, and UV light sensitivity.

Alternatives

Using a homemade mixture of baking soda and lemon juice may potentially be harmful to the skin. Instead, a person can try using neutral cleansers or chemical peels that contain AHAs, such as glycolic acid.

Neutralizing stomach acid

Excess stomach acid can cause uncomfortable symptoms, such as heartburn, vomiting, and indigestion.

Many people with excess stomach acid take over-the-counter (OTC) antacids to relieve their symptoms. Consuming baking soda and lemon juice together may also neutralize stomach acid in a similar fashion as an antacid.

A 2017 study examined the antacid effects of various foods. The authors of this study created artificial stomach acid with a pH of 1.2. Although lemon juice by itself had almost no effect, sodium bicarbonate successfully neutralized the synthetic stomach acid.

Many OTC antacids contain sodium bicarbonate and citric acid. Lemons and other citrus fruits are rich sources of naturally-occurring citric acid.

When a person mixes lemon juice and baking soda, the citric acid reacts with the sodium bicarbonate to produce a buffer called sodium citrate. A buffer refers to a weak acid or base that prevents drastic pH changes. Although lemon juice does not neutralize stomach acid, it may help stabilize the pH level inside the stomach.

Alternatives

Using baking soda and lemon juice to combat excess stomach acid may be a good home remedy, as effective OTC antacids contain similar ingredients.

However, mixing the correct proportions of baking soda and lemon juice can be difficult.

Consuming a mixture with too much baking soda may cause diarrhea and gas, whereas too much lemon juice could trigger acid reflux and make symptoms worse. Purchasing an antacid at the drug store is often much safer.

Other home remedies for reducing excess stomach acid include:

  • avoiding or reducing acidic foods and beverages
  • limiting caffeine intake
  • limiting alcohol consumption
  • eating smaller meals
  • drinking more water
  • getting enough sleep

People with severe or persistent acid reflux or heartburn should speak to a doctor or gastroenterologist.

Xylitol: Uses, effects, and possible benefits

by

Xylitol is a sugar alcohol, which is a type of carbohydrate and does not actually contain alcohol. Xylitol occurs naturally in small amounts in fibrous fruits and vegetables, trees, corncobs, and even the human body.

Manufacturers use xylitol as a sugar substitute because its sweetness is comparable with that of table sugar but with fewer calories.

Xylitol is a common ingredient in many products, from sugar-free chewing gum to toothpaste. People also use xylitol as a table-top sweetener and in baking.

In this article, we look at the uses and potential health benefits of xylitol. We also cover its side effects, drug interactions, dosage, and alternatives.

Uses

Xylitol has a similar level of sweetness to sugar but with a fraction of the calories. It is a popular ingredient in a variety of products, including sugar-free gum and toothpaste.

Manufacturers add xylitol to a range of foods, including:

  • sugar-free candies, such as gum, mints, and gummies
  • jams and jellies
  • honey
  • nut butters, including peanut butter
  • yogurt

Xylitol is also an ingredient in some dental care products, including:

  • toothpaste
  • mouthwash
  • other fluoride products

Xylitol sweeteners are available to purchase online.

Potential benefits

Xylitol has several potential health benefits, including:

Low glycemic index

Xylitol has a low glycemic index (GI). This means that consuming it does not cause spikes in blood glucose or insulin levels in the body. For this reason, xylitol is a good sugar substitute for people with diabetes.

Due to its low GI, xylitol is also a weight loss-friendly sugar substitute.

Also, a 2015 study revealed that xylitol had significant blood glucose-lowering effects in rats that ate high-fat diets.

Dental health

Xylitol is an ingredient in many dental hygiene products, including toothpaste and mouthwash. This is due to the fact that xylitol is non-fermentable, which means that the bacteria in the mouth cannot convert it into the harmful acid that causes tooth decay.

The oral bacterium Streptococcus mutans is largely responsible for plaque, which is the sticky, white substance that can accumulate on the outside of a person’s teeth.

Plaque binds lactic acid against the surface of the tooth. This acid breaks down the enamel and leads to tooth decay.

While it is normal for people to have some plaque on their teeth, excess amounts can lead to tooth decay, cavities, and gum disease.

A 2017 systematic review suggests that xylitol reduces the amount of S. mutans bacteria in the mouth, which reduces the amount of plaque and may help prevent tooth decay.

A 2014 study examined the effects of xylitol on Porphyromonas gingivalis, which is the bacterium responsible for gingivitis, or gum disease. If left untreated, excess amounts of P. gingivalis can move into the bloodstream and lead to systemic inflammation.

In the study, scientists grew samples of P. gingivalis in a laboratory and added them to human cell cultures pretreated with xylitol. They saw that xylitol increased the production of immune system proteins and inhibited the growth of the bacteria.

Side effects and safety

The United States Food and Drug Administration (FDA) have approved xylitol as a food additive. Xylitol is generally safe, but like other sugar alcohols, it can cause digestive issues such as bloating and diarrhea in some people.

It is worth noting that xylitol can be very toxic to dogs. It is vital to store products containing xylitol in a safe place that pets cannot reach. Anyone who thinks that their dog has consumed xylitol should call their veterinarian or the Animal Poison Control Center immediately.
