🦷 5 Oral Care Ingredients to Avoid – And What to Use Instead

(Plus: A Deep Dive into Safer Teeth Whitening Strips)

Oral care is the foundation of a confident, healthy lifestyle. But not all products are created equal — many popular toothpaste and whitening strips contain ingredients that can do more harm than good.

Whether you’re buying for yourself or your child, knowing what to avoid (and what to embrace) empowers you to build a smarter daily routine — free from irritation, enamel damage, or toxic additives.

Let’s explore 5 common ingredients to avoid — and their healthier, evidence-based alternatives — with a special focus on whitening strips.

1. Sodium Lauryl Sulphate (SLS)

🚫 Why to Avoid It:
SLS is a foaming agent used in many commercial toothpastes and some whitening strips. While it helps distribute the product evenly, studies show it can cause oral irritation, ulcers, and canker sores, especially in people with sensitivities (PubMed).

✅ Safer Alternative:
Choose SLS-free toothpaste made with gentle surfactants that respect your oral tissues and microbiome.
✨ Elty Daily Care Toothpaste is SLS-free and uses pine tree extract for a refreshing, antibacterial clean — without the burn.

2. Artificial Sweeteners & Flavourings

🚫 Why to Avoid It:
Ingredients like aspartame, saccharin, and artificial mint flavors may not be acutely toxic but have been linked to gut microbiome disruption and allergic reactions in sensitive individuals (NCBI).

✅ Safer Alternative:
Look for formulas with xylitol, a natural sweetener that actively helps fight cavities and is safe for kids.
✨ Elty Kids Chocolate Milkshake Toothpaste contains no artificial sweeteners or preservatives, and is kid-approved for its safe-to-swallow formula.

3. Hydrogen Peroxide & Carbamide Peroxide (in Whitening Strips)

🚫 Why to Avoid It:
These common whitening agents are effective but come with significant downsides:

Tooth sensitivity and enamel weakening with repeated use
Gum irritation and chemical burns in high concentrations
Potential toxicity if accidentally swallowed (NCBI Study)

✅ Safer Alternative:
Use PAP+ (Phthalimidoperoxycaproic Acid) — a peroxide-free compound clinically proven to whiten teeth without sensitivity or enamel damage.
✨ Elty Whitening Strips contain PAP+, hydroxyapatite for enamel repair, and soothing botanicals like chamomile.

4. Polyvinylpyrrolidone (PVP)

🚫 Why to Avoid It:
This polymer is used in many strips to help them stick to your teeth. However, some people experience allergic reactions or oral irritation, and its long-term impact in daily oral use isn’t well-studied (ScienceDirect).

✅ Safer Alternative:
Elty Whitening Strips are free from PVP, using a gentle adhesion method with minimal residue and no allergens.

5. Chlorine Dioxide

🚫 Why to Avoid It:
Some low-cost whitening products use chlorine dioxide to bleach teeth — the same chemical used to disinfect swimming pools. This compound can strip enamel, increasing the risk of decay and long-term sensitivity (American Dental Association).

✅ Safer Alternative:
Only trust dentist-formulated strips using PAP+ and remineralizing agents like hydroxyapatite. Elty’s formula is non-abrasive, non-toxic, and safe for regular use.

Bonus: What Else to Look for in Safe Oral Care

✔️ Hydroxyapatite: A natural mineral that strengthens and remineralises enamel — shown to be as effective as fluoride, without toxicity (Source)
✔️ Fluoride-free for kids: Especially important for toddlers who may swallow toothpaste
✔️ Free from alcohol and dyes: These can dry out the mouth or irritate tissues
✔️ Dentist-designed: Formulas co-developed with dental professionals offer both safety and science-backed efficacy

💡 Final Word: Not All Whitening Strips Are Created Equal

Most over-the-counter whitening strips still rely on peroxide and chemical adhesives that whiten temporarily but damage over time. With Elty Whitening Strips, you get a peroxide-free formula that:

Whitens gradually and gently
Repairs enamel with every use
Leaves no residue and no sensitivity

They’re the ideal choice for anyone looking to upgrade their routine without compromising their health.
