Killing Bacteria

To kill bacteria building up in your mouth, rinse it out with a salt and water solution. If the pain is too great, use lukewarm water. If you can stand it, it is best to use hot. Mix one part salt to three parts water and gargle it like mouthwash.
A word of warning: the salt may cause the tooth to sting! However, it will subside soon. If you are worried about that, reduce the amount of salt by half.

You can also apply salt directly around the area of the affected tooth and rinse it out. Whatever you do, do not place the salt directly on the tooth itself, especially if you suspect that you may be suffering from exposed roots.
Garlic also has a lot of antibacterial properties that could help relieve your toothache. In this case, you can chew on a clove of garlic or mince it and place it around the tooth area. If you can stomach the taste, you could also try gargling with a garlic, salt and water mixture.
You can make an easy homemade garlic solution by combining minced garlic, salt and water. Soak a cotton ball in this mixture and place it on the gum line or on the tooth.
Another natural antibacterial solution commonly found in all households is vinegar. Rinsing your mouth out with vinegar will kill the bacteria and dilute the pain.
Choose apple cider or organic vinegar since it has the highest amount of bacterial killing properties. Dilute the vinegar with 2 parts water before gargling it. You can also choose to gargle it pure.
Another option is to dab it on the tooth using cotton buds. You can also choose to soak a cotton ball in vinegar and bite on it.
If you cannot stomach the taste of vinegar, lemon juice is a viable alternative. Drink the lemon juice with water, but do not add sugar. The sugar will only worsen your toothache.

Boiled guava leaves are a lesser known folk remedy that can also help relieve pain. Using guava as an antiseptic is popular in the Pacific Rim and around Southeast Asia.
Prepare the leaves by washing them thoroughly. Boil them with water until the water is at a rolling boil. Place the leaves on the tooth. These are also effective for open wounds and skin allergies.
Limes and onions also have high doses of vitamin C and natural antiseptic properties that help kill bacteria when eaten. The onion must be eaten raw for this to be effective. The high dose of vitamin C also helps fight and prevent infection. If you naturally love onions, this is great news.
Alleviating Pain Naturally
Herbal and home remedies can reduce and remove the pain from a toothache. These are great alternatives for people who are unable to take chemical pain relievers for health reasons.
Like modern medicine, one must be very careful when using herbal remedies. Remember to check with your doctor or dentist before using any of the following supplements.
Clove oil is one of the most common remedies for an aching tooth. Clove oil is distilled from the spice and is regarded as an effective analgesic and antiseptic. If you do not have clove oil at home, stop by your neighborhood drug store or pharmacy. They usually have it in supply.
 Relieve Toothache Pain Quickly
Consider asking for a diluted solution since clove oil in its purest form can cause a painful stinging sensation.
Soak a cotton bud in clove oil and place it in your mouth, preferably on the painful tooth. Try mixing the clove oil with a bit of water and pepper. Massage these into your gums to numb them and ease pain.
Chew on a fresh clove as a substitute if you do not have immediate access to clove oil. It works just as well.
A word of caution: do not give pure clove oil to your children. It can cause serious side effects in large quantities. If you are on blood-clotting medicine, clove oil may increase the chance of bleeding. Otherwise, clove oil is generally regarded as safe to take by the FDA.
Another common herbal antiseptic is the bayberry. Like clove oil, it has been commonly used as pain reliever for centuries. It is commonly used to relieve cold symptoms.
Bayberry’s strong antiseptic powers make it an excellent rinse for pre and post dental surgery. Bayberry bark paste can be applied directly on the tooth.
Because the herb is very strong, pregnant and breastfeeding women should refrain from using bayberry. People with kidney and heart diseases should consult their doctors before using this herb.
Asafoetida is a gum extracted from a species of fern that has strong antibacterial properties. The gum should be combined with lemon juice and pounded to a fine paste in a mortar and pestle before applying it to the tooth.
Like bayberry, asafoetida should not be ingested by pregnant or nursing women as it is a known contraceptive. It may cause miscarriages.
