Dental Implants. Very Early Infection?

Without photos, this is just a guess: this is normal healing of the gums.  Infection takes time to "incubate" so I would not think it is that.  As gums heal from surgery, they often appear white.  They may even slough off an outer layer or two.  Within two weeks it should look close to normal.

Without a photo, it's hard to say. If you're concerned about infection, the best course of action would be to follow up with the dentist so he or she can evaluate the area. When the site is healing, a normal white-ish substance called "granulation tissue" can form, and this is normal. Hope this helps.

Without photos hard to determine but many times I get calls from patients and they come in concerned and it turns out that it is normal.  As gums heal they normally appear white.
