In one sentence, describe what the following article is about: Skin tags are simply abnormal growths of your skin that tend to be the same color as your skin. They are usually very small but can be as large as 1 centimetre (0.39in) in diameter in some cases. If a skin tag gets irritated, such as if clothing rubs on it repeatedly, they can turn pink or red. Skin tags are typically not painful unless they have been rubbed or irritated in some way. Most commonly this is done when a piece of jewelry or clothing rubs against them repeatedly. However, a growth that is painful can signal some other type of growth, such as a cyst or a small skin cancer. Because of this you should have painful growths looked at by a doctor. If you have a growth that is painful, bleeding, draining, or rough, have it looked at by your primary care physician or by a dermatologist. Either type of doctor can usually determine whether the growth is a skin tag or not. If it's determined that the growth is not a skin tag, you will likely be referred to a dermatologist to find out what the growth is, why it is painful, and what treatments can be done to eliminate the pain. While skin tags are benign and harmless, it is a good idea to have changes to your skin looked at by your doctor or by a dermatologist. When you have your yearly routine exam, tell your doctor about any changes on your skin so that they can evaluate them. They will be able to tell you definitively whether or not a growth on your skin is a skin tag and whether you need to have them treated. If your doctor cannot diagnose a skin tag just by looking at it, they may have a biopsy done on it. This entails removing the skin tag and having the cells in it looked at under a microscope. Just because a skin tag is harmless doesn't mean that you want it on your body. Talk to your doctor about having a skin tag removed if it is irritated and causing you pain, or if you don't like the look of it on your skin. Skin tags can be removed with an incision or by freezing them off with liquid nitrogen. It is more likely that the removal procedure will be covered by medical insurance if it is causing your pain and discomfort than if you simply don't like it cosmetically.
Summary: Look for a small growth on your skin. Assess whether the growth is painful or not. Have all skin abnormalities looked at by a doctor. Have skin tags removed if you like.

Problem: Article: Baking soda is a mild abrasive that can scrub plaque and surface stains off of your teeth. You can apply it to your teeth as a whitener in a number of ways: Dip a dampened toothbrush directly into powdered baking soda. Brush your teeth as you normally would, spit out the baking soda, and rinse your mouth with water. Make a paste of baking soda and water. Put some baking soda in a small container that you can close (to store the paste). Slowly stir water a few drops at a time into the baking soda until a smooth paste forms. Apply to your toothbrush, then brush and rinse your teeth as normal. Baking soda might irritate the tissues of your mouth. If you notice any inflammation or soreness, use this treatment less frequently. Baking soda combined with hydrogen peroxide makes a very effective teeth whitener. This treatment, however, should not be used frequently. Hydrogen peroxide can irritate the tissues of your mouth, and prolonged use may cause serious problems. To make this whitener: Pour a teaspoon of baking soda into a bowl or small dish. Stir five to seven drops of hydrogen peroxide into the baking soda until a smooth paste forms. You can also add a drop of peppermint extract to improve the flavor of the mixture. Apply to your toothbrush, then brush and rinse your teeth as normal. Be sure to spit out all of the peroxidedo not swallow it. Rinse your mouth well afterwards. Since the citric acid found in lemon juice is a natural bleaching agent, it can make a great whitening agent. You can make a paste by combining the two ingredients, and use it infrequently as a whitener. Pour a teaspoon of baking soda into a bowl or small dish. Stir lemon juice a few drops at a time into the baking soda until a smooth paste is formed. Apply the paste to your teeth (using a finger is fine) and let it sit for two to three minutes. Rinse your teeth with water afterwards. Use this treatment no more than once a week, as citric acid can also damage the enamel of your teeth, and irritate the tissues of your mouth. Vinegar is acidic, like lemon, and so it can help to whiten your teeth, especially when combined with baking soda. A mixture of the two can be used as a paste to brush your teeth clean. Pour a teaspoon of baking soda into a bowl or small dish. Stir vinegar a few drops at a time into the baking soda until a smooth paste is formed. Dip a dampened toothbrush in the paste and brush as normal. Rinse your mouth with water afterwards.
Summary:
Use baking soda directly on your teeth. Make a paste of baking soda and hydrogen peroxide. Mix baking soda and lemon juice. Make a paste of baking soda and vinegar.
