Can I get a new smile for 5k ? It's mainly my 4 front teeth at the top ?

While doing only 4 teeth is certainly an option, it will be very limiting and not really a "new smile".  If you seek a brighter color, 4 will stand out.  To avoid this you would need to choose between matching the color to the adjacent teeth, or bleaching the adjacent teeth first and THEN matching.  This DOES bring up issues of metamerism and bite force management, etc...As far as fees, only each dental office can answer that.  Fees vary from office to office.

In my opinion, you can definitely achieve a new smile within your budget. If course it will depend on the particular dentist who treats you. You may want to call a few local dentists and compare their prices once you have determined your options for dental treatment.Best of luck,James Asaf, DDS

Yes, you can. It may involve you having the dentist to prioritize a treatment planfor you that fits your budget, but it is possible to remain in that price range. The first step is getting an appointment and having the dentist perform a new patientComprehensive exam with x-rays. This will help him in achieving the ideal plan for you and your budget. Then he can prioritize the treatment plan keeping in mind your number one concern andif at all possible placing it as priority 1.
