Understanding Mouthwash: Choosing the Right One for Your Smile

At Dr Michael Handler Dentistry, we often get asked, “Should I be using mouthwash?” The answer is: it depends on your oral health goals. Mouthwash can be a helpful part of your dental routine—if you’re using the right one the right way.

Let’s take a closer look at the different types of mouthwash available, what they do, and how to use them properly.

Types of Mouthwash & Their Uses

1. Cosmetic Mouthwash

Purpose: Freshens breath

What it does: Masks bad breath temporarily but doesn’t treat the cause

Best for: A quick breath freshener before a social event or meeting

Tip: Cosmetic mouthwash does not replace brushing or flossing.

2. Therapeutic Mouthwash

These rinses go beyond freshening—they help treat or prevent oral health issues.

a) Antibacterial/Antiseptic Mouthwash

Purpose: Reduces plaque and gum inflammation

Key ingredients: Chlorhexidine (prescription only), essential oils, cetylpyridinium chloride

Best for: Gum disease, post-surgery healing, or bad breath due to bacteria

Note: Prescription rinses like chlorhexidine should only be used short-term due to potential staining and altered taste.

b) Fluoride Mouthwash

Purpose: Strengthens enamel and helps prevent cavities

Best for: Kids (age 6+), adults prone to tooth decay, and those with braces

How to use: Swish and spit—then wait 30 minutes before eating or drinking

c) Desensitizing Mouthwash

Purpose: Reduces tooth sensitivity

Active ingredients: Potassium nitrate or arginine

Best for: Sensitive teeth, post-whitening sensitivity, exposed roots

d) Alcohol-Free Mouthwash

Purpose: Offers protection without the burn

Best for: People with dry mouth, sensitive tissues, or who prefer an alcohol-free option

Mouthwash Do’s and Don’ts

DO

- Use the recommended amount (usually 20 mL)

- Swish for at least 30 seconds

- Use daily or as directed by your dentist

- Follow with brushing and flossing for best results

DON’T

- Swallow mouthwash

- Eat or drink right after using fluoride or antibacterial rinses

- Use in place of brushing and flossing

Is Mouthwash Safe for Kids?

Most mouthwashes are not recommended for children under 6. For children 6 and older, fluoride rinses may be helpful—but only under supervision to avoid accidental swallowing.
