How to unlock the The Orthodontist achievement in Shadows of the Damned - Definitive Guide
If you haven't gotten this achievement by the time you get to the Third Grim sister then you are still in luck, after you kill the Third Grim Sister you will get the upgrade to The Dentist, so make sure you get this during your fight with her.
During the fight it requires you to shoot her in the face, do this and she will turn the room to darkness, instead of shooting her chest let her drop the 3 or 4 demons on to the floor then shoot the Goat head above her on the wall.
Doing this allows you to net 3 or 4 demons over and over again as long as you do not shoot her chest.
You can do this with the Skullfest 9000 and the HotBoner also.
The Teethgrinder - Unlocked at the end of Act 3-3, selectable via
Replacing The Teether, you'll now be able to shoot Demon Teeth at twice the speed thanks to its multiple barrels. As with the Teether, Johnson will be covered in blue flames when selected and its source of ammo are Demon Teeth, which can be found in blue chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 30 enemies with The Teethgrinder to unlock the trophy.
You will pick up this upgrade in chapter 3-3. Nothing fancy to this just kill 30 demons. I chose to do this on the second playthrough and do the shotgun achievements on the first playthrough but it is advised to pick one. Any kill shot with this gun will count even if you have damaged them with another gun first.
