If you live in San Diego and you do not have the best dental insurance HMO you do not have many different options, you have to look for an option or be willing to pay a lot for a dental service.
This is my experience in my first trip to a dentist in Tijuana Mexico, before I crossed the border I left my car in a parking lot that is only one block away from the border, next to the shopping plaza, open 24hrs, there are two more parking near, the prices between them does not vary much, in this link you can see the page of the parking lot where I leave my car.
The time I took the Uber to the dentist was 10 to 15 minutes, there is not much traffic, the dentist who had already contacted him by phone days before, is located very close to the border, so the cost of the Uber was $ 3.55 dollars, very cheap compared to San Diego.
To be my first trip to Tijuana I highly recommend
I highly recommend that you take your dental treatment in Tijuana, it is a good option that will save you a lot of money and they are also very good dentists in Tijuana.
