Article: White shirt collars tend to pick up built-up dirt, oils, and haircare products from the back of your neck, leading to grungy, yellowish discoloration. The next time you plan to put on a white shirt, jump in the shower first and give the back of your neck a good scrub with soap or body wash. If you don’t have time for a shower, wash the back of your neck with a soapy washcloth or a cleansing wipe before putting on your shirt. If you tend to use hair products (such as gel or wax) or skincare products (like lotions or moisturizers), wipe the back of your neck before putting your shirt on. These products can easily pick up dirt and grime, and some may contain staining ingredients. Let any hair product dry before putting on your shirt, especially if your hair is long enough to touch your collar. The major culprit behind those aggravating yellow underarm stains is not your sweat, but the aluminum used in many deodorants and antiperspirants. A chemical reaction between sweat and aluminum creates the yellow discoloration. To prevent this problem, switch to a natural, aluminum-free deodorant that focuses on combating bacterial odors rather than blocking your pores.  Look for deodorants that say “aluminum free” on the label, or make your own deodorant using household ingredients and essential oils. Some antiperspirants are formulated to both reduce sweating and prevent yellow stains. Look for deodorants that say something like “anti-yellow staining” or “fights stains on shirts” on the label. To fight wetness without shirt-staining aluminum, combine an aluminum-free deodorant with a sprinkling of absorbent Gold Bond or a little baby powder. Undershirts provide a barrier of protection between your shirt and your body. They may be particularly useful for preventing underarm stains. If you perspire a lot, look for undershirts with built-in sweat guards. Having a lot of armpit hair promotes excess sweating, especially when the weather is hot. Protect your shirts from sweat stains and reduce your need for staining antiperspirants by removing some or all of your underarm hair. Catching and treating stains early is key to preventing them from taking hold. As soon as you notice discoloration starting to develop on your shirt’s collar or underarms, use a commercial pre-laundry stain treatment on the area. Wash or dry clean your shirt as soon as possible. Enzyme-based cleaners are especially good for tackling sweat stains.

Article: You do not need to remove your jewelry when you brush your teeth. In fact, if you remove it, you run the risk of irritating your tongue or having the piercing close up. Tongue piercings heal much quicker than many other piercings, so don't risk removing jewelry at first. Besides, fresh piercings make your tongue too tender to touch. Tongue piercings heal within 6 to 8 weeks on average. After that point, you can remove the piercing whenever you want. Try taking it out when you eat or brush your teeth to help keep it clean. Toothbrushes collect bacteria over time, so getting a new brush reduces the chances of infection. Look for slim toothbrushes designed to reach small spaces. Slimmer soft-bristled brushes are useful for brushing both your teeth and your piercing. Stop at your local drug store or general store to get a new toothbrush. Brushes are inexpensive compared to the cost of discomfort and medical treatment for an infection. Starting at the back of your mouth, position your toothbrush with the bristles facing the roots of your teeth. Take care of the inside portion of each tooth first. Work from the back to the front and repeat with your other row of teeth. Avoid the piercing for now, especially if you just had it put in. New piercings make your tongue very sensitive. Try to avoid it as best you can by holding the toothbrush at an angle. The swelling goes away after 7 to 10 days. Instead of using a back and forth motion, move in small circles. This cleans your teeth effectively without damaging the enamel or hitting your piercing. Continue doing this for a few minutes to ensure you remove all plaque and debris. Brush the inside, outside, and top of each tooth to keep your smile healthy.  As you brush, roll or sweep the toothbrush down from the tops of your teeth to direct the debris into your mouth. Don’t rush! Rushing is tempting, but quick brushing may leave debris that can wear down your teeth or get into your piercing. For great teeth, reach for your toothbrush about half an hour after every meal. This is especially important while your piercing heals, since it clears away plaque and food particles that can lead to an infection. However, stay hygienic by making it a part of your routine even after your mouth goes back to normal.  Acidic foods wear down your teeth if you brush right away after eating. Some examples of acidic food include grains, sugar, fish, some meat, and sweetened drinks. Drinking water after eating or brushing before you eat are ways to protect your teeth.  Frequent brushing is a great way to keep your teeth in shape and avoid some tense visits to the dentist. Keep in mind, though, that brushing too hard or too frequently can wear down enamel. After brushing, floss the space between your teeth as you normally do. Take extra care while working on the areas close to the hole in your tongue. Knocking your hand against it could be painful.

Leave jewelry in place until the piercing heals. Use a new toothbrush when you first get your piercing. Hold the toothbrush at a 45-degree angle to avoid bumping the piercing. Brush your teeth using circular motions for 2 to 3 minutes. Brush your teeth 3 times a day after eating.
