Is it ok to take decadron, tylenol, and amoxicillin 500mg together? i had dental surgery and was prescribed these medications together?

The three do not interfere with one another. They can be used as stated.

You trusted the Dentist to do surgery on you. Trust him/hern to prescribe the correct medication. Take antibiotic exactly as directed until the entire course has been completed (don't skip pills/don"t quit before pills run out). Thenother meds are for pain management. Begin to taper off as your post-operative pain diminishes. If you have medication questions is b esgt to contact your Dentist

I don’t see any adverse reaction from this regimen. If there will be anything related to your medical condition or if you are taking other medication, your pharmacist should be able to flag them and alert you and your treating doctor to find a replacement. If in doubt Ask your pharmacist. Stay safe and get better soon.
