Avoiding Cavities: What People Used to Swear By and What Still Makes Sense
Figuring out how to get rid of cavities isn’t as simple as searching for a quick fix online. Once decay has started, there’s no true “home cure” that replaces a dentist’s work. But that doesn’t mean you’re powerless. There are plenty of ways to protect your teeth, strengthen enamel, ease pain, and stop things from getting worse - all using simple, time-tested home remedies.
Home Remedies: How to Get Rid of Cavities
We don’t eat a lot of sugary foods, and for the most part, we eat a healthy diet. But for the first time in years, I went to the dentist and was told I had a cavity. I was like, “What?!” I honestly thought cavities were a thing of the past - kind of like how the hair on my legs doesn’t grow much anymore. That’s what led me to start looking into how to get rid of cavities, especially since my dental insurance doesn’t cover fluoride treatments. We’re also on a private well, which means no added fluoride in our water. I already use fluoride toothpaste and a fluoride gel (maybe not enough) at home, but I wanted to know if professional fluoride treatments are really necessary - or if natural care can help fill in the gaps. It really depends on how prone you are to cavities and how well your everyday habits protect your enamel.
Oil Pulling
An old Ayurvedic practice using sesame or coconut oil.
- How it’s done: Swish a tablespoon in your mouth for 10 to 20 minutes, then spit it out (not in the sink).
- Why people do it: Believed to “pull” toxins and bacteria from the mouth, reduce plaque, and freshen breath.
- Reality check: Modern studies show it can reduce bacteria, but it won’t “heal” cavities - it may help prevent them from worsening.
Salt-Water Rinse
A tried-and-true old remedy.
- How it’s done: Dissolve 1/2 tsp of salt in a cup of warm water; swish for 30 seconds.
- Why it helps: Creates an alkaline environment that can discourage bacterial growth and soothe inflamed gums.
Clove Oil
A long-standing natural toothache remedy.
- Use: Dab diluted clove essential oil (1 drop in 1 tsp carrier oil) on a cotton ball and apply to the sore tooth.
- Why it helps: Contains eugenol, a natural numbing and antibacterial compound.
- Old wives’ tale twist: Some believed sleeping with a clove under your pillow kept toothaches away - charming, but skip this.
Baking Soda Brushing
Grandma’s natural toothpaste.
- Use: Mix baking soda with a few drops of water into a paste.
- Why it helps: Gently whitens and neutralizes acids that eat at enamel.
- Note: Too abrasive for daily use; once or twice a week is plenty.
Cut Back on Sugary Foods and Drinks
It’s one of the simplest (and most effective) ways to protect your teeth. Sugar feeds the bacteria that cause cavities, and every time you sip or snack on something sweet, your enamel takes a hit.
- What to do: Try to limit frequent snacking, skip the sticky candies, and rinse or brush after eating sweets.
- Bonus tip: Swap sugary sodas for sparkling water or herbal tea - your teeth will thank you.
Use a Water Flosser or Waterpik
A water flosser or Waterpik can reach places your toothbrush can’t, washing away food and bacteria between teeth and along the gumline.
- How often: Once a day is plenty for most people - twice if you’re prone to buildup.
- What to fill it with:
- Plain warm water – gentle and safe for daily use.
- Salt water – helps reduce bacteria and soothe gums (1/2 tsp salt per cup).
- Hydrogen peroxide mix – half peroxide, half water, used occasionally (once or twice a week) to disinfect and whiten. Don’t swallow it.
Always rinse the reservoir after use so it doesn’t harbor bacteria.
Brush for Two Full Minutes
It sounds basic, but brushing long enough makes a huge difference. Most people only brush for 30 to 45 seconds, which leaves plaque behind.
- Try this: Divide your mouth into four sections and spend about 30 seconds on each.
- Tools that help: A soft-bristled brush and a fluoride toothpaste (or your fluoride gel) keep enamel strong without being abrasive.
- Timing: Twice a day - once in the morning, once before bed - is the gold standard.
Don’t Skip Regular Dental Checkups
Even if you’re focused on how to get rid of cavities with home remedies, regular dental checkups are still essential for keeping your teeth healthy.
- Why it matters: Dentists can spot small issues before they turn into painful cavities or infections.
- How often: Most people do well with a visit every six months, but if you’re prone to cavities or gum issues, every 3 to 4 months can help, the dentists office will usually let you know a good time frame.
- Tip: Use your visits to ask about fluoride treatments, enamel-strengthening options, or ways to manage sensitivity naturally between appointments.
Herbal Helpers
Old remedies often used herbs for their antibacterial properties:
- Neem sticks: Used for centuries in India to clean teeth.
- Licorice root: Traditionally chewed for its cavity-fighting properties.
- Guava leaves or sage tea: Used as mouth rinses in folk medicine.
Calcium and Vitamin D-Rich Foods
Not exactly an “old wives’ tale,” but nutrition counts.
- Why it matters: Your body can remineralize early enamel damage if you get enough calcium, D, and phosphorus.
- Examples: Cheese, leafy greens, eggs, sardines, mushrooms, sunlight.
Old Wives’ Tales
Although these may seem fun – they are a little questionable:
- “Whiskey on a toothache” – numbs pain temporarily, but dries out tissue.
- “Rub garlic directly on the tooth” – antibacterial but can burn gums.
- “Put an aspirin on the tooth” – do not do this; it can erode tissue.
- “Charcoal brushing” – trendy again, but too abrasive long-term.
No home remedy can fill or reverse a true cavity once decay has broken through the enamel.
But they can:
- Soothe pain and inflammation.
- Reduce bacteria.
- Slow or stop early demineralization.
- Support gum and tooth health naturally.
Fluoride Treatments: Necessary or Not?
This is where modern science meets old-fashioned prevention. Fluoride helps rebuild enamel that’s been weakened by acid, which can slow or even reverse early decay before it turns into a full-blown cavity.
- At-home fluoride use: Using fluoride toothpaste and gels (like I do) gives you regular protection - great for people on well water or without insurance coverage.
- In-office fluoride treatments: These contain a higher concentration and are applied directly after cleaning. If your insurance covers it, it’s worth doing once or twice a year, especially if you get cavities easily or have sensitive teeth.
- Without fluoride: You can still strengthen enamel by focusing on mineral-rich foods (calcium, phosphorus, magnesium), xylitol toothpaste or gum, and limiting acids and sugars that erode enamel.
How to Get Rid of Cavities
When it comes to how to get rid of cavities, there’s no magic fix - but there’s a lot you can do to protect your teeth and keep decay from advancing. Combining home remedies like salt rinses, clove oil, and oil pulling with fluoride toothpaste (and possibly a professional fluoride treatment if you can get it covered) gives you the best of both worlds.
In the end, good oral health isn’t just about what your insurance covers - it’s about consistency and regular dental checkups. Whether you’re using a simple homemade rinse or brushing with a fluoride gel before bed, those small daily choices can make a big difference in keeping your teeth strong, healthy, and pain-free.
