We need mouthguards for contact sports

WALT: write a persuasive speech.

Mouthguards are mandatory to some sports.  Mouthguards are also worn to play sports that involve grounds and stadiums.  Mouthguards are made of soft plastic.  The way mouthguards are made are to protect someones mouth.  

Mouthguards protect your teeth.  Losing teeth is bad because you won’t be able to eat and talk properly.  Mouthguards also cushion your teeth so you can play better at sports.  Mouthguards help prevent damage for your teeth so it does not get chipped or loose teeth.  

Mouthguards protect against jaw injury and neck injury.  Your jaw and neck are important to a person's body because if your neck breaks, you might go to the hospital or get killed.  You also need to protect your jaw so you can eat food.  If your jaw is broken you won’t be able to open your mouth for a couple of days or weeks.

Mouthguards also reduce concussion.  Concussion is when you get hit hard on the head and you get knocked out.  Knocked out is bad because if you're in a middle of a game you, can get trampled on.  Concussion also make you get brain damage.  If your brain gets damaged, you might forget things and your brain might be seriously damaged.

I can see from the reasons I have given above that everyone who is involved or play sports  with contact, need to wear mouthguards.  If people ignore this rule, they will get hurt.
