For the last 2 days, I've been experiencing slight pain on my front tooth. It's like a little hint of pain that feels more like sensitivity and then it goes away and doesn't bother me for the rest of the day. I put ice on it to see if it would hurt and it doesn't. When I bite down it doesn't hurt and even when I put pressure on it with my finger, it feels completely normal. Is this something I should worry about?
