DIY Baking Soda and Coconut Oil Toothpaste: Benefits & Homemade Recipes

If you’re seeking a safer, chemical-free way to clean and whiten your teeth, baking soda and coconut oil could be your answer. These two simple kitchen ingredients offer powerful oral care benefits. In this post, we explore their combined benefits and offer three DIY toothpaste recipes.

Why Use Baking Soda and Coconut Oil on Your Teeth?

• Naturally whitens teeth by removing surface stains
• Neutralizes bad breath-causing bacteria
• Helps reduce plaque buildup
• Gentle on enamel when used correctly
• Free from synthetic chemicals and fluoride

The Science That Supports These Ingredients

Baking Soda (Sodium Bicarbonate): Mildly abrasive, it scrubs away plaque and stains without damaging enamel when used sparingly. It also helps neutralize acids in the mouth, reducing cavity risk (1)(2)(3).
Coconut Oil: Contains lauric acid, a compound known for its antimicrobial properties. Studies show it may reduce Streptococcus mutans, a key bacteria behind tooth decay (4)(5).

How Do These Ingredients Contribute to Oral Health?

• Lauric Acid in Coconut Oil fights bacteria, improves gum health, and may reduce plaque.
• Sodium Bicarbonate lifts stains and keeps mouth pH balanced, limiting harmful bacterial growth.
• Together, they offer cleansing, whitening, and antibacterial benefits in one natural paste.

When to Discontinue Use

• If you experience gum irritation, tooth sensitivity, or any burning sensation, stop using the paste.
• Overuse of baking soda can wear enamel if used too frequently.
• Discontinue if your dentist advises against abrasive agents for your teeth.

Adjusting Ingredient Quantities Based on Needs

• For Sensitive Teeth: Use more coconut oil and less baking soda.
• For Whitening Focus: Increase baking soda slightly, but use less often.
• For Oil Pulling Texture: Add more coconut oil and a drop of peppermint oil.
• Always test a small amount first and observe how your mouth responds.

Is This Safe to Use Daily?

Yes, but with caution.

• Use 2–3 times a week to avoid over-abrasion.
• Not suitable as a complete replacement for fluoride toothpaste in all cases.
• Best used as a natural supplement to your regular brushing routine.
