In this article, I'll explain everything you need to know about NOBS Toothpaste Tablets is the best toothpaste for canker sores.

First, what causes canker sores?

Not to be confused with cold sores, horrible canker sores from toothpaste can arise due to various factors and ingredients to avoid in toothpaste.

Sodium Lauryl Sulfate (SLS), a common foaming agent found in many toothpaste formulations, is known to cause irritation and trigger mouth sores in susceptible individuals. This compound can strip away the natural protective layer of saliva on the gums, resulting in dryness and irritation.

As a result, SLS is one of the most commonly avoided ingredients in toothpaste. In fact, the need to prevent canker sores has given rise to a many SLS free toothpastes, like NOBS Toothpaste Tablets.

Additionally, some people may experience allergic reactions to certain ingredients in toothpaste, such as flavorings or preservatives, leading to the development of mouth sores, swelling, or redness in the oral cavity.

Let's walk through some of the key causes of most canker sores from toothpaste.


SLS in Toothpaste

SLS is commonly included in toothpaste for its surfactant properties, which help create foam and lather. This foaming action helps you distribute toothpaste throughout your mouth during brushing which allows it to reach areas that might otherwise be difficult to access.

Additionally, SLS enhances the cleaning efficacy of toothpaste by effectively removing debris, food particles, and plaque from the teeth and gums. However, while SLS can be beneficial, it can have some bad side effects in toothpaste.

Thankfully, as technology has progressed, we now have newer, more gentle surfactants that can be found in SLS free toothpastes as compared to SLS containing toothpaste.


Abrasive ingredients present in toothpaste, like charcoal, can exacerbate oral tissue irritation and potentially contribute to the formation of mouth sores and cause recurrent canker sores. These abrasives, while effective at removing surface stains and plaque, can be harsh on the delicate tissues of the mouth when used excessively or aggressively.

Can toothpaste cause canker sores?

Yes, toothpaste can potentially cause canker sores in some individuals. Certain ingredients in toothpaste, such as sodium lauryl sulfate (SLS), can contribute to the development of canker sores.

SLS is a surfactant commonly found in toothpaste that can irritate the delicate tissues inside our mouths, causing canker sores (also known as aphthous ulcers) to form. These frequent canker sores are often accompanied by an unpleasant tingling or burning sensation.

Additionally, abrasive substances in toothpaste can also contribute to tissue irritation and ulcer formation, further exacerbating the risk of developing canker sores.

If you experience recurrent canker sores and suspect your toothpaste may be the cause, consider switching ton SLS free toothpaste to see if it helps alleviate the issue.

In this article, I'll explain everything you need to know about canker sores and whether or not your toothpaste might be causing them.

For those of us who frequently suffer from canker sores, finding the right oral care products can be the key to managing discomfort and promoting healing.

NOBS Toothpaste Tablets are the standout canker sore toothpaste choice for those prone to these painful ulcers. One of the key reasons is that they're an SLS-free toothpaste, meaning they're not formulated with any sodium lauryl sulfate.

Sodium lauryl sulfate is a common ingredient in many toothpastes that has been linked to the exacerbation of canker sores and mouth ulcers. By eliminating SLS and harsh abrasives from their formula, canker sore toothpastes like NOBS Toothpaste Tablets offer a gentler cleaning experience, reducing the potential irritation that can trigger or worsen canker sores.

Also, NOBS Toothpaste Tablets have a simple, clean ingredient list, featuring only 13 ingredients. This minimalist approach minimizes your risk of allergic reactions which can be a concern with other toothpastes.

Key Ingredients in NOBS Toothpaste Tablets

The 13 Ingredients of NOBS Toothpaste

NOBS Toothpaste Tablets are a unique type of SLS free toothpaste that is jam-packed with ingredients included to nurture your oral microbiome. This unique formula makes it the best toothpaste for canker sores.

Let's walk through some of these key ingredients.

Nano Hydroxyapatite

Nano hydroxyapatite (also known as nHA) is a synthetic form of hydroxyapatite, a naturally occurring mineral found in our teeth and bones. It's known for its similarity to the mineral component of our teeth, making it a valuable ingredient in remineralizing toothpaste.

Nano hydroxyapatite is created by breaking down hydroxyapatite into nanoscale particles, which are extremely small and have unique properties. Because of this small size, its primary benefits include its ability to:

  • remineralize tooth enamel

  • repair initial stages of tooth decay

  • strengthen the tooth structure

  • and soothe tooth sensitivity.

These benefits occur because when nano hydroxyapatite is applied to the enamel surface, it can bond with the tooth's natural hydroxyapatite, repairing and strengthening the enamel.

Studies suggest that nano hydroxyapatite is equally as effective as fluoride toothpaste at remineralization and preventing dental caries. Due to some of the concerns around fluoride toxicity, many people prefer nano hydroxyapatite as a better alternative to fluoride.


Xylitol Toothpaste

Xylitol in toothpaste is a sugar alcohol used as a natural sweetener and for its oral health benefits. Unlike traditional sugars, xylitol does not feed the bacteria in your mouth, which means it doesn't contribute to tooth decay.

In fact, xylitol actively fights against cavity-causing bacteria, like mutans streptococci, and can prevent tooth decay by inhibiting their growth and reducing their ability to create acids that erode our enamel.

This lowers our risk of developing dental caries and promotes good dental health. That said, xylitol cannot reverse cavities.

Further, xylitol stimulates saliva production, which is beneficial for our oral health. Saliva is our natural buffer against acids that can otherwise demineralize enamel and cause tooth decay.

Because of these properties, xylitol is considered one of the best ingredients in toothpaste. Plus, its naturally sweet taste also makes toothpaste more enjoyable use to without the harmful effects of sugar, making it a popular choice for both adults and kids toothpaste.

Zinc Citrate

Zinc citrate in toothpaste is an ingredient valued for its oral health benefits, particularly its role in fighting plaque and reducing bad breath.

Zinc is a naturally occurring mineral that, when formulated as zinc citrate, becomes an effective agent against the growth of bacteria in the mouth. These bacteria are responsible for plaque formation, gum disease, and the production of volatile sulfur compounds (VSCs) that lead to bad breath.

By inhibiting the growth of these bacteria, zinc citrate helps to reduce plaque buildup, decrease the risk of gingivitis (gum inflammation), and combat halitosis (bad breath). Its antibacterial properties make it a common addition to toothpaste and mouthwashes, enhancing their ability to maintain oral hygiene.

Additionally, zinc citrate can contribute to remineralizing tooth enamel, offering further protection against decay.

Sodium Bicarbonate

Sodium Bicarbonate

Baking soda, also known as sodium bicarbonate, in toothpaste serves as a gentle yet effective cleaner for your teeth, offering multiple benefits for your oral health.

Its mild abrasive qualities help scrub away surface stains from your teeth, contributing to a brighter, whiter smile without damaging the enamel. This makes baking soda toothpaste an excellent choice for daily use, especially if you're looking to remove stains caused by coffee, tea, wine, or tobacco.

Further, baking soda's natural alkalinity plays a crucial role in neutralizing the plaque acids in your mouth. These acids, produced by bacteria as they digest food particles, can erode tooth enamel and lead to cavities.

By keeping the oral environment more balanced, baking soda not only protects your enamel but also supports overall gum health.

Additionally, baking soda tackles bad breath by addressing its root cause: the acidic by-products of oral bacteria. By neutralizing these acids, baking soda helps freshen your breath, leaving your mouth feeling cleaner and more refreshed.

For those with sensitive teeth, brushing teeth baking soda toothpaste can be a gentler alternative, effectively cleaning without causing discomfort.
