I am a general dentist in mid career.
Your scope of practice is only limited by your skills, training, and experience.
At this stage in my career I am comfortable performing many procedures that are commonly referred to specialists.
As an example, today, my first pt was a maxillary edentulation from premolar to premolar, with extensive alveoplasty, and delivery of an immediate denture. Done under local with N2O sedation. I trimmed the models prior to denture processing (after wax try in) for maximum control over final shape of his maxilla. Many would refer to an oral surgeon for a procedure where you are flapping the entire alveolus, and performing extensive osteotomy/ aleveoplasty with rotary and hand instruments, and fitting the alveolus to the final prosthetic. This particular pt had large over jet and his maxilla had large buccal tuberosities and undercuts. Achieving an ideal final prosthetic result both functionally and esthetically required the experience to see the final result BEFORE we got there, and extensive planning to execute.
The next several hours were several fillings, exams, and simple extractions, and was still able to squeeze a crown prep into my 3rd chair. My last pt was a teenager who had facial trauma and splinting of his anterior teeth several years ago at another office. One of his lateral incisors was experiencing external/internal resorption, and one of his centrals was necrotic, with an immature apex. I performed the endo on the central, very easy to instrument due to the huge canal, but there was NO apex or apical stop and would have been impossible to obturate using conventional techniques. I obturated the apical 4mm with MTA, and will obturate the rest of the canal in 2 weeks. As in the above case which many would refer to OS, many would refer this to endo. I took a photo of my apical obturation and texted it to my endodontist for critique afterwards, as I have picked up many pointers from him over the years, even popping in and observing on many half days when I finished early. Then surgical extraction and socket debridement, degranulation of the lateral, with placement of a collagen based socket preservation graft, for a future implant, which I will place when the pt is older.
Pretty fun day, I would say!😉
This is not to say that there are not days where I seem to have 5 pts in a row for operative dentistry (fillings), which I do find very tedious and not the most fun, lol.
With all of this said, if I had to do it over again, I probably would have specialized (I graduated in the top 10% of my class, ranked 4th in my class my senior year). After many years of doing this I finally understand why most of the kids in my class who had fathers who were general dentists, ended up specializing if they had the grades to get in - general dentistry IS hard work. And you have to be married to your pts. This is great for the ones that are nice that you look forward to seeing, but for the ones that are miserable and like to inflict their mood on you and your staff, it is no fun, lol.
