Broadly, this is the difference between twice and double:

Twice = Adverb - modifies verb, adjective or another adverb
Double = Adjective - Modifies noun

Twice can be used to answer "How/how many" one did something. Double is used to show "what" one did.

I ran to the store twice.
I bought double books than usual.

Experts recommend that one visit one's dentist two times a year or whenever any unusual pain or bleeding occurs.

A. Experts recommend that one visit one's dentist  two times  ---> there is no grammatical mistake, but twice is better and more formal than two times.
B. Experts recommend that one visit one's dentist twice ---> Correct
C. Experts recommend that  one  visit  their  dentist twice ----> pronoun-antecedent disagreement error. one(singular) doesn't agree with their(plural)
D. Experts recommend that  one  visit  his  dentist twice ---> B is better than D.
E. It is recommended by experts that one visit one's dentist two times ---> Incorrect. Unneccessarily wordy.

I found multiple comments on another answer on GMAT club by  sayantanc2k  and others, I have just combined them to give a somewhat correct answer. Hope it helps everyone searching for difference between  Twice and double  like I did.

Twice or two times could be used for two different meanings:

1.frequency (because of the word times)

2.multiple x2, as mentioned below.
My age is double your age.
My age is twice as your age.
I am two times as old as you.

However double can only be used to refer to the multiple x2.

Ex. The stock prices of the company  DOUBLED  when they rose sharply  TWICE  in the same day.
