Ouch! One of the worst feelings I can think of is taking a bite into your evening dinner and being hit with tooth pain. The severity of an aching tooth can be from achy to mild to sharp to excruciating pain. And there is nothing like it happening on a weekend or a holiday when one cannot get to the dentist for tooth pain relief. This really is something not to be taken lightly.
What is one to do? Well, there are several ways to ward off the pain until you can see the dentist. You could take pain killers such as Paracetamol, ibuprofen or aspirin. There are also many natural remedies that people use including garlic or an ice pack. You just apply these to the area affected. A combination of these should work miracles. My personal preference is clove oil. If I don't have any to hand I use cloves on the tooth. Or you can even make a warm tea from cloves which you can rinse around your mouth. Hopefully one of these methods has cured your tooth pain.
So let's consider why you had the pain in the first place. It could be the tooth has become broken or chipped or it may be decaying. There could be a problem with the gums of even the bone around the tooth. The nerves around your teeth are extremely sensitive and could become exposed or damaged. You may have pain caused from your jaw or any of the muscles in your mouth for example if you have knocked it.
If you have a filling in your mouth it could have cracked due to heat or just from being worn. From years of brushing you may have exposed tooth much of the tooth and the gums could have resided to expose the root, which will then be very sensitive when you have hot or cold food. It could be something more serious such as tooth or jaw pain from Angina or a type of heart disease. The point here is because you don't know the reason the best advice I can give is to visit your dentist as soon as possible. We are all told from an early age to brush and floss to help with tooth pain relief and to visit your dentist regularly and I would encourage you to continue with your routine.
Your teeth are an important aspect of your health and being healthy means being happy, you need to live your life to the full and prevent the need for tooth pain relief.
