Short answer: probably no, unless you have an immunodeficiency or are susceptible of endocarditis (e. g. if you got a heart transplant).
Exceptions are:
Implant surgery, where a single dose 1 hour prior the operation can be considered and some periodontal surgeries or extractions where the surgeon had to manipulate the bone
And in case of an invasive dental treatment is followed by fever and/or malaise.
In details a lot of articles suggest that antibiotics are not normally necessary, unless you have cardiac disease or susceptible of having one (e. g. if you have received a transplant or in case of immunodeficiency). For more info
