Megaklinikka

This is like the fast-​food of dentistry.
PROS: You can make an appointment online for which time slot you prefer (which is just below 20 euros to make and is cheaper than calling them to do it). You will get a confirmation ½ hour before the appointment time via SMS to confirm it too (a nice friendly reminder, which I like).
You can usually be seen within 24 hours and will be typically in and out within an hour so if you are just swinging by during your lunch hour, you will make it back to work on time.
The place itself is EXTREMELY easy to get to. Conveniently located next to Kamppi.
The people are extremely efficient and friendly. The place itself feels very sterile and clean (which is reeeeally important for any medical area).
Very cheap — especially if you have the Kela card. The list of prices is on their website though so very easy to see what you’ll be paying.
CONS: I got an infected tooth and the wisdom tooth next to it removed. I was given no care instructions or painkillers even though my head was pounding and I felt like I’d been shot in the face.
The wisdom tooth hole got infected within 24 hours and I got feverish, chilly and nauseous. Thankfully, my aunt is a doctor and was able to get me a prescription for antibiotics and painkillers. However, since I hadn’t been to the dentist in a while, I didn’t know it could be serious and the dentist there really should have forewarned me, especially since it appears to be pretty typical for wisdom teeth to get infected and it could cause serious harm if left untreated and if infection gets into blood stream.
Again, I WILL come back just because of the prices and quick service. I do think some more care could be put into the patients though. It seems like their focus is getting the patients in and out as fast as they can.
