I have recently had a root canal on one of my front teeth due to a knock to the tooth. The toot has darkened very slightly and I am wanting to know the safest most successful way to whiten the tooth. I dont want a veneer or crown as i dont want the tooth to be weakened any further - i want the tooth to remain as strong and long lasting as possible. I am in my 20s so I really want my perfect smile back.
