Hey Girlie,
I was a body piercer for several years and have had my tongue pierced for 15 years. Everyone so far has given pretty good advice. Here's my two sense.....
As far as the piercing itself goes...
First and foremost if you are seriously interested in getting one, make sure the shop is reputable and clean, ask to see the piercer's portfolio, ask to see their autoclave and while the piercer is setting up be sure to look at the instruments packaging. The instruments and needle should be in long white packaging. On the back side of the packaging you should see brown arrows. The arrows on the packaging are typically blue or pink before sterilization, after they have been sterilized the arrows turn brown. Also look around for biohazard containers, they are usually red, this is where the used needles are disposed of. If you see these things at the shop you can be pretty sure that the shop takes the necessary precautions to keep you safe from communicable disease. Cross contamination is also a big factor so it might be a good idea to ask what their setup and break down procedures are. Any good piercer or tattooist will be happy to share that info. with you. This is your body and your safety comes first.
The next thing I will tell you is of utter importance is the aftercare. You are 100% responsible for the healing of your piercing and to rid yourself of any chance of infection and reduce the swelling and increase healing time you should do as follows.
Note: These instructions are for tongue and completely internal oral piercings only! Other piercings such as labret, monroe, madison, lip etc- these instructions can be used for the inside of your mouth. Piercings that involve the outside of your face have additional instructions.
For the first 3 days or so, only eat soft foods. Your barbell initially should be surgical stainless steel. Gold is a possibility but initially, I recommend stainless steel. Gold is a very porous metal and can harbor more bacteria. It is still safe, however, I am a purist and this is my preference. I saw that someone urged you to get a plastic barbell, DO NOT get pierced with a plastic barbell!!!!!! Once your piercing has healed, by all means go for a plastic barbell if you wish. Plastic is very easy to scratch and the balls are easily broken, stripped or cracked. Because of this, you increase your risk of infection and possibly losing your piercing as soon as you get it. If you leave your piercing out for more than a few minutes, it is quite possible that you will not be able to get it back in.
Keep a bottle of listerine or if you choose a non alcohol mouthwash such as Biotene on you at all times. Anytime you put anything in or around your mouth, even water, rinse with mouthwash. If you touch your mouth, rinse with mouthwash. Be sure to tighten the balls daily. When you do so be sure to wash your hands and then rinse with mouthwash. If you think you are overdoing the mouthwash, its still probably not enough. Keep you using the mouthwash.
You should also rinse one to two times daily with non-iodized sea salt. This is very soothing and increases your healing time. I typically recommend once in the morning and once before bed. For the first few days, it is a good idea to use Ibubrofren to help with swelling but do not use aspirin. Aspirin is an anticoagulant will thin the blood therefore causes more bleeding. Do not drink or use aspirin within 24 hours of getting pierced or tattooed. It is safe to do so, but again, will reduce the amount of bleeding alcohol also thins the blood. Also do not use straws while drinking fluids during the first days. Straws can increase your chance of removing necessary blood clots and can cause bleeding. Sucking on anything too hard can also cause aggitation. You can eat cold foods such as ice cream or popsicles but do so gently. The cold will soothe and feel really good. Avoid, spicy foods at all cost!!!!
It is safe to brush your teeth but be careful. Try to schedule your piercing over a 3 day period when you don't have to do a lot of talking. Talking, playing or moving your tongue a lot will increase your swelling. So try to keep your mouth as inactive as possible. I will also say this, until your tongue has fully healed. Abstain from kissing and oral sex. People mouths are disgusting and harbor more bacteria than you want to know about. Including your own. You do not need the introduction of more bacteria than you already have. As far as the oral sex goes, bacteria again is a factor, but the action your mouth takes could possibly tear, aggravate, and irritate your piercing and cause issues. Its better to hold off. The tongue is a high blood flow area so it is one of the quickest healing piercings to get. Usually you are good to go after 2 weeks. I have seen as long as a month. Either way listen to your body. You will know what you are ready for. Especially when it comes to eating.
As I said before, your piercing will take anywhere from 2 weeks to 1 month to fully heal. During this time, do not play with it, it will increase swelling and can cause tearing. When you first get your piercing, the barbell will be about an inch and a half in length. It needs to be this long to allow for your tongue to swell. This is normal. And yes, your tongue will swell that much. It will swell from ball to ball. It is extremely uncomfortable. However, not unbearable. Once your piercing has healed you can switch to a shorter barbell and if you so desire, you can switch to a different material.
Ok, now onto the aftermath, damage to teeth and so forth.
I worked in a dental clinic and after having an extremely large barbell in my mouth for 15 years I can honestly say the damage is minimal. Especially with a standard 14 gauge barbell. I asked a ton of questions addressed to many Dentists who looked at my mouth and I was very fortunate. I did experience some receeding of my gums but nothing astronomical. My teeth are in tact and have had no harm come to the inside of my mouth, so the dentists tell me. And this is coming from someone who had a 2 guage bar and balls the size of m&m's in my mouth for 15 years. I stretched mine and loved it. Most people stay with a 14 or go to a 12 for comfort. In the time that I had my piercing I think I only cracked down on it while eating less than a handful of times. No big deal. However, it is totally possible for you to have a different experience. People have had issues, such as cracked teeth, receeding gums, infection and so forth. But in my experience, if a person's tooth cracked, it was going to crack anyway....eventually. In most cases, I have seen chips to the teeth and minimal wearing down of the enamel. I am sure there are worse cases than what I have outlined here but I am speaking strictly to my personal experience. Please note....RESULTS MAY VARY!!!!!!
If you need any other questions or concerns addressed about after care or anything about the procedure give me a call sweetie, I will be happy to help.
Hope this was helpful to anyone considering this procedure. Keep your piercings clean ladies and gents, your body will thank you!!!!
