Making aloe vera mouthwash at home takes about five minutes and requires just a few ingredients. The basic formula is 1 cup of aloe vera juice mixed with half a cup of distilled water, two teaspoons of baking soda, and about ten drops of peppermint essential oil for flavor. But the details matter, especially which type of aloe you use and how you handle it, so let’s walk through the full process.
Why Aloe Vera Works as a Mouthwash
Aloe vera isn’t just a folk remedy for oral care. A randomized controlled trial published in the Journal of Clinical and Experimental Dentistry found that aloe vera mouthwash was equally effective as chlorhexidine, the gold-standard prescription mouthwash, at reducing both plaque and gingivitis. Participants using aloe vera saw statistically significant improvements in plaque scores and gum inflammation compared to a placebo group, with no meaningful difference between the aloe vera and chlorhexidine groups.
Aloe vera also shows antimicrobial activity against several bacterial strains that contribute to oral infections. The gel contains compounds that reduce inflammation and support tissue healing, which is why it’s been studied for gum disease specifically. The baking soda in the recipe adds mild antibacterial and odor-neutralizing properties, making the combination particularly useful for freshening breath.
Choosing the Right Aloe Vera
This is the most important step, and the one most recipes gloss over. You have two options: store-bought aloe vera juice or fresh gel from a leaf. Each requires different preparation.
Store-Bought Aloe Vera Juice
The easiest route is purchasing inner-leaf aloe vera juice from a health food store or online. Look for products labeled “inner fillet” or “decolorized,” which means the manufacturer has already removed a compound called aloin. Aloin is a yellowish latex found just beneath the outer rind of the leaf, and it acts as a harsh laxative. Even in a mouthwash you spit out, residual aloin can irritate your mouth and stomach if any is swallowed. Commercially processed aloe juice goes through filtration and activated carbon treatment to strip out these compounds, making it much safer for oral use.
Fresh Aloe From a Leaf
If you want to use a fresh aloe leaf, you need to carefully separate the clear inner gel from the green rind and the yellow latex layer underneath it. Start by cutting off the base of the leaf (about an inch from the bottom), the pointed tip, and the spiny edges along both sides. Then lay the leaf flat and slice off the top and bottom rind, similar to filleting a fish. You’ll be left with a translucent slab of inner gel.
Rinse this gel thoroughly under running water to wash away any remaining yellow residue. That yellow liquid is the aloin-containing latex, and you want none of it in your mouthwash. Once rinsed, blend the gel until smooth. Fresh gel won’t keep as long as store-bought juice, so plan to use or refrigerate your mouthwash promptly.
The Basic Recipe
Here’s what you need:
- 1 cup aloe vera juice (or blended inner-leaf gel)
- ½ cup distilled water
- 2 teaspoons baking soda
- 10 drops peppermint essential oil
Combine the aloe vera juice and distilled water in a clean glass jar or bottle. Add the baking soda and stir or shake until it dissolves completely. Then add the peppermint oil and mix again. Use distilled water rather than tap water because it’s free of chlorine and bacteria, which helps the mouthwash stay fresh longer.
To use it, swish about two tablespoons around your mouth for 30 seconds to a minute, then spit. You can use it once or twice a day, ideally after brushing.
Variations and Add-Ins
The base recipe works well on its own, but you can adjust it depending on what you’re after. If peppermint is too strong or you’re sensitive to it, try tea tree essential oil (three to five drops) instead, which has its own antimicrobial properties. A teaspoon of xylitol can add mild sweetness while also discouraging bacterial growth on your teeth.
If you find the baking soda taste unpleasant, you can reduce it to one teaspoon. The trade-off is slightly less odor-neutralizing power. Some people also add a small splash of hydrogen peroxide (about a teaspoon of the 3% solution you’d find at a drugstore) for extra whitening and antibacterial action, though this can cause mild irritation if used daily.
Storage and Shelf Life
Homemade mouthwash doesn’t contain the preservatives found in commercial products, so it has a shorter shelf life. Store it in a sealed glass container in the refrigerator. A batch made with store-bought aloe vera juice typically stays good for one to two weeks. If you used fresh gel, aim to use it within a week. Discard it if you notice any cloudiness, off smell, or unusual texture.
Making smaller batches more frequently is a better strategy than making a large supply. The recipe scales down easily: half a cup of aloe juice, a quarter cup of water, one teaspoon of baking soda, and five drops of peppermint oil.
Who Should Be Cautious
Aloe vera is generally well tolerated when used as a rinse-and-spit mouthwash, but there are a few situations to be aware of. People who are allergic to plants in the lily family (which includes onions, garlic, and tulips) may react to aloe vera with skin irritation, hives, or redness around the mouth. If you’ve never used aloe topically before, test a small amount on the inside of your wrist and wait 24 hours before putting it in your mouth.
Pregnant and nursing women should be especially careful to avoid swallowing any of the mouthwash. Aloe latex contains compounds that can stimulate uterine contractions, and certain components may pass into breast milk and cause digestive upset in infants. Even with a spit-and-rinse product, accidental ingestion is possible, so the cautious approach is to stick with a commercially tested mouthwash during pregnancy and breastfeeding.
If you notice any irritation, burning, or an allergic reaction after using your homemade rinse, stop using it. The essential oils are a common culprit, so try a batch without them first before ruling out the aloe itself.
How It Compares to Commercial Mouthwash
The main advantage of a homemade aloe vera rinse is what it leaves out. Most commercial mouthwashes contain alcohol, artificial dyes, and strong detergents that can dry out your mouth and irritate sensitive gums. Aloe vera offers comparable plaque and gingivitis reduction without that burning sensation or the drying effect of alcohol-based formulas.
The main disadvantage is consistency. A commercial product delivers a precise concentration of active ingredients every time. Your homemade version will vary slightly batch to batch, especially if you’re using fresh leaves. It also won’t contain fluoride, so it’s not a replacement for fluoride toothpaste if cavity prevention is a priority. Think of it as a complement to brushing and flossing rather than a substitute for any part of your routine.
