Hi
The experience will be what you choose to make it. Our perceptions drive our beliefs and actions. I am not being harsh or critical. The terror you feel is real, but you are the one that is causing it. As long as you entertain feelings of dread the fear will grow. Let's look at the positive.
Dentists perform thousands of these procedures everyday. They are safe and a proven procedure, not experimental. The success rate is very high and they solve problems that would other wise result in tooth loss.
The procedure is not dangerous and be done with just LA. It is your best option to save the tooth.
There is not anything that will transpire that you cannot deal with. The LA will take care of any pain or discomfort. Healing is fairly quick. Ask yourself the following questions.
How much will it mean to you to save the tooth?
What do you gain by saving the tooth?
What is it about the procedure you fear?
What do you believe will happen?
What conditions do you need to change in your mind to drop the fear level?
How would a person that does not fear this procedure behave? What thoughts would they have? What view of this would they keep? How would they act? What is the difference between you and them?
The procedure would be the same for both of you. The difference is in the perception. If you want to achieve the results of a successful person, do what they do, percieve what they percieve. Success leaves clues.
The absolutely worse thing that can happen is you need to have the tooth extracted, less than 15% chance. The best is that the procedure works and the tooth is saved with no more problems 85-88% percent chance.
If you had an 85-88% chance of winning a bet, would you do it? Yes, I bet you would. Those are huge odds in you favor. If Las Vegas offered those odds, they would not be there they are way too good.
I believe in positive actions. Anxiety is best dealt with by looking at the situation for what it is and not through the fear. The fear does not have you best interest at heart. I t is like a monster that wants to be fed.
You can reduce your anxiety by changing your perceptions. You can be successful. Believe in yourself and your abilities.
Blessings
