Pericoronitis (the infection around the wisdom tooth) occurs when the tissue surrounding a wisdom tooth becomes inflamed and infected. It can be caused when only part of the tooth has "erupted" into the mouth, or if crowding near the wisdom teeth has made flossing and proper cleaning difficult. To figure out whether your wisdom tooth is infected, it is important to be able to identify the tell-tale signs and symptoms. Look for the following: Bright red gums or red with white spots on your gums. The gums will be inflamed around the particular tooth. Moderate to severe pain in your jaw and difficulty chewing. You may notice swelling that looks like a small lump in your cheek. The swollen area may also feel hot to the touch. An unpleasant, metallic taste in your mouth. This is caused by the blood and pus at the site of the infection. You may also experience bad breath as a result. Difficulty opening your mouth or swallowing. This may mean that the infection has spread from the gums to the surrounding muscles. Fever. A temperature above 100 degrees F (37.8 degrees C) indicates that you have a fever, which means that your body is fighting off an infection. In severe cases, the infection may be accompanied by muscle weakness. If this is the case, you should contact a dentist or doctor immediately. In some cases, the root may also be infected. If this is the case, your dentist will likely extract the tooth. Salt is naturally antiseptic. Using a saltwater rinse can help kill bacteria in your mouth. Add to 1 teaspoon of salt to 8 ounces of lukewarm water. Mix well to combine. Take a mouthful of the rinse and swirl it around your mouth for 30 seconds, concentrating on the infected area to kill the bacteria. Spit out the salt water after 30 seconds do not swallow. Repeat this process 3 to 4 times per day. You can use this treatment in combination with any antibiotics your dentist prescribes. Depending where you live, it might possible to buy antibacterial dental gels at your local drugstore. These gels help to control the infection and alleviate any pain or inflammation. To apply the gel, rinse your mouth thoroughly and apply one or two drops of the gel directly onto the infected area using a cotton applicator tip. Don't use your fingers to apply the gel as you risk introducing more bacteria. Apply the dental gel 3 to 4 times per day for best results. If you are experiencing severe discomfort as a result of the wisdom tooth infection, you can take a pain reliever that also relieves inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) are usually available over the counter at pharmacies and drug stores. Ibuprofen (Advil, Motrin), naproxen (Aleve), and aspirin are the most common NSAIDs. Do not give aspirin to children under age 18, as it has been linked to the development of Reye's Syndrome, which causes brain and liver damage. Acetaminophen (paracetamol) is not an NSAID and does not reduce inflammation, but it can help relieve pain. Follow the dosing instructions on the packaging, or as instructed by your doctor, and do not exceed the maximum dosage. Keep in mind that each drug has its own list of side effects, so read the product advice information on the packaging before taking any medication. Talk to your pharmacist or doctor if needed. If you don't want or can't take medication, apply an ice pack to the infected area. It will relieve pain and reduce the inflammation until you can seek treatment. If the swelling is severe, seek emergency medical treatment. Pour ice cubes in a plastic bag or in a towel. Press the bag against the painful area for at least ten minutes. You can also use a bag of frozen vegetables, such as peas or corn. (Don't eat bagged veggies that have been thawed and refrozen.) It is very important that you schedule an appointment with your dentist as soon as possible. If you do not get adequate medical treatment for your infection, it could spread to other parts of your mouth and body. Pericoronitis may also lead to other complications such as gum disease, tooth decay and the development of cysts. More severe complications include swollen lymph nodes, sepsis, systemic infection, and possibly even death. If your dentist is too busy to see you immediately, visit an urgent care clinic or go to the hospital. Many have emergency dentists.

Summary: Identify the signs. Rinse your mouth with saltwater. Use a dental gel to relieve pain and inflammation. Relieve the pain. Use an ice pack. Call your dentist.

Posh people have good manners and know the boundaries in human relations. Always say "please" and "thank you" when the situation calls for it. Say "excuse me," greet people politely, and display good table mannerssuch as chewing with your mouth closed. Also do not use your phone at the table or when talking to someone. Although posh people are often wealthy or "high class," this does not mean they are arrogant. It's important to be confident in yourself and your abilities, but do not think that you are better than anyone else. Treating everyone you meet as your equal is very posh. Always show up and do your best at anything you commit to. For example, if you say you will throw a party for someone, do it and do it to your best ability. Or, if you make a mess while you're a guest at someone's home, make sure to clean up after yourself. Posh people have a large vocabulary and know when to employ it. However, posh people never force words into sentences that don't belong. Read and study to expand your vocabulary, but don't use your knowledge to show off. Speak clearly and confidently. This person could be a friend, historical figure, or even a celebrity. Don't copy them precisely but do allow their way of being, their style, and attitudes have some influence on yours. That way, you can build a strong foundation on which to become a posh person in your own right. Some examples of posh people are Emma Watson, Kate Middleton, Benedict Cumberbatch, and Eddie Redmayne. A posh accent is often associated with the English aristocracy, as well with educational institutions, like Oxford. This accent is referred to as posh, but is actually called Upper Received Pronunciation English (Upper RP). Essentially, to sound this way, practice an English accent. Then, pronounce your consonants more fully. Also, pronounce vowels sound leaning more towards the "e" sound. For example, when saying "man," it will sound more like "men" in a posh accent. Also, a weak "I" sound will sound more like an "e." For example, "quickly" should be pronounced more like "queckly."
Summary: Display good manners. Avoid an arrogant attitude. Take responsibility for your actions and obligations. Be articulate. Look for posh people you admire. Practice a posh accent.
