I've had implants for my upper six front teeth* for 20+ years. Never a problem. Only regular dental visits and daily cleaning. No other maintenance required. In fact, they are better than my natural teeth which have had crowns, filling replacements, cracking teeth, etc.
Did a dentist perform your implant surgery? If so, maybe consult a periodontist (specialist).
Maybe it's the placement of the implant? Is don't think the upper front teeth gets as much wear and tear/pressure as the back teeth do.
*I grew up with my two eye teeth missing, so very large gaps between my front teeth. Yes, the mean kids called me pumpkin face.
