At Mr. and Mrs. Tooth Dental Clinic, we recommend SLS-free toothpastes for patients with sensitive gums, dry mouth, or those prone to mouth ulcers. Sodium Lauryl Sulfate (SLS), a common foaming agent, can cause irritation and worsen conditions like gingivitis or aphthous ulcers. SLS-free toothpastes provide a gentler, non-irritating clean, making them ideal for long-term use and promoting better oral health without the harshness of traditional toothpaste ingredients.
