10 Tips To Fight Tooth Decay And Keep Your Pearly Whites Healthy

Home remedies for tooth decay include using guava leaf paste and a sage mouthwash.

Our teeth chomp through a variety of food day and night. But we don’t really give them a second thought till a gaping hole in a tooth or a stabbing twinge makes their presence felt. Cavities don’t develop overnight but are a result of prolonged tooth decay over time. But the good news is it is possible to stop and even reverse tooth decay in the initial stages!

Tooth decay occurs when harmful bacteria that cover your teeth in a thin film (plaque) produce acids using sugars from foods. This acid eats away at your tooth enamel, eventually leading to a cavity or hole in the tooth. Minerals like phosphate and calcium present in your saliva and even fluoride from water or toothpaste can replace minerals lost during an acid attack and help repair tooth enamel. In fact, even after you get that tell-tale early sign of tooth decay – a white spot where your tooth has lost minerals, it is possible to reverse the damage. To ward off cavities and tackle tooth decay, try these simple remedies and tips which tackle harmful bacteria or help with tooth remineralization.2

1. Limit Sugary And Sticky Foods

The harmful bacteria present in your mouth use sugar to produce teeth-damaging acid, so sugary foods can increase your chances of getting a cavity. Foods with added sugar like soda, juice, candy, toffee, and cookies help produce enamel-destroying acid that accelerates tooth decay. Foods that stick to your teeth are also offenders as they stay in touch with your teeth for a longer period.3


2. Avoid Frequent Snacking

When you snack frequently, your teeth are exposed to foods that can be used to produce acids that destroy your enamel. This means your teeth face an acid attack before they’ve had a chance to remineralize after the last time you ate. Also, your mouth produces less acid-fighting saliva during snacking as opposed to regular meals. Sipping on sugary or flavored drinks also has the same impact. These factors together may set you up for tooth decay. Cut down on snacking between meals to limit the number of acid attacks on your teeth and to give them time to remineralize.4 5

3. Rinse Your Mouth After You Eat

Good oral hygiene can also go a long way in halting tooth decay. Rinse out your mouth with plain water after you eat something to dislodge food particles stuck in your mouth. This can also reduce bacteria in your mouth by as much as 30%.6 Brushing twice a day and flossing should also be a part of your daily routine to keep your teeth healthy and prevent decay.


4. Use A Guava Leaf Paste

Guava leaves have antibacterial properties and have been found to work against common oral pathogens such as Streptococcus mutans. Flavonoids like guaijaverin and quercetin present in the leaves are thought to be responsible for their antibacterial effect. Grind tender guava leaves into a paste and apply that to your teeth to get rid of harmful bacteria. Gently rub with a finger and rinse afterward. You can also make a simple mouthwash by boiling 4 to 5 leaves in water and adding a little salt.7 Use this twice a day.

5. Rinse With A Sage Mouthwash

You may know sage as a culinary herb but it also has antibacterial properties and is effective against oral bacteria. Beneficial compounds such as 1,8-cineole, thujone, and camphor are thought to account for this effect. Take a teaspoon of this dried herb, crush it, and add to salt water for an antibacterial mouthwash. Swirl around in your mouth for about 5 minutes 2–3 times a day to tackle teeth-damaging bacteria.8 9


6. Try A Lemongrass Oil Mouthwash

According to a study where the participants used a 0.25% lemongrass oil mouthwash twice a day for 21 days, it worked effectively against plaque as well as gum inflammation. In fact, it was found to be comparable to chlorhexidine, a common antibacterial mouthwash. Lemongrass contains many compounds like limonene, linalool, citral, citronellal, and geraniol which may work to prevent the formation of bacterial biofilms on teeth.

Mix 2–3 drops of aromatic lemongrass oil in a cup of water to prepare an effective antibacterial mouthwash.10


7. Oil Pull With Sesame Oil

Oil pulling is an ancient technique recommended in ayurveda for tackling oral pathogens. And research indicates that it can decrease dental plaque and gum inflammation. This process involves swishing edible oils such as sesame oil or even coconut oil which act against oral pathogens in your mouth.11 12

Here’s how you go about it. Take a tablespoon of coconut or sesame oil into your mouth and suck and pull it between your teeth for around 10 to 15 minutes. The oil should turn milky white in color by then. Now spit out the oil. Take care not to swallow the oil since it now contains germs from your mouth.


8. Use A Fluoride Toothpaste Or Mouthwash

Fluoride is a mineral that’s naturally present in our body as well as in many foods and water. It helps in the remineralization of teeth and makes the enamel harder. So using a fluoride toothpaste or mouthwash can help counter tooth decay. Toothpaste for adults should ideally contain around 1350 parts per million fluoride.13 14

But while fluoride can help keep your teeth healthy, like other minerals and vitamins, it can be harmful if consumed in excessive amounts. Therefore, experts recommend that children under 2 should not use fluoride toothpaste as they’re likely to swallow it and exceed the amount that can be consumed at their age. Also, because of the intense controversy and (unresolved) debate around fluoride usage especially in water, whether or not you would try this remains a personal choice.


9. Chew Sugar-Free Gum

Chewing sugar-free gum can also enhance remineralization. It stimulates the flow of saliva, which plays an important role in fighting tooth decay. Saliva helps restore lost minerals from your teeth since it contains trace amounts of phosphate and calcium. In fact, around 20 minutes after you have something to eat, saliva starts to reduce the effect of acids attacking your teeth.15

One study found that using a xylitol chewing gum 4 times a day for a week significantly improved remineralization of caries-like lesions present on teeth. The presence of xylitol, funoran, and calcium hydrogen phosphate made it work much better than plain gum since xylitol, a sugar alcohol, reduces dental caries, while funoran, a compound extracted from red seaweed, inhibits oral bacteria. Calcium hydrogen phosphate enhances the concentration of calcium and phosphate in saliva.16

10. Have Yogurt

A Japanese study that looked at 3-year-old children observed that those who consumed yogurt 4 times or more a week had significantly less dental caries than those who had it less than once a week. This beneficial effect could be due to the presence of calcium which can help in the remineralization of teeth.1718 So go ahead and add yogurt to your daily diet to fight tooth decay.
