The pinhole surgical technique (PST grafts) is a revolutionary new way of correcting serious gum line recession. It has many advantages over previous methods, and yet for all that, it doesn't always get the attention it deserves.
When you are short on gum tissue, your teeth are bound to suffer. First of all, it badly distorts your natural smile. But more importantly, it exposes your tooth roots to bacterial attacks that can end in root canals or even total tooth loss.
When dealing with too much gum tissue, you would need to consider crown lengthening as a periodontal solution; but when too little or wrongly placed gum tissue is the issue, your two major options are gum grafts plus stitches or PST grafts.
It pays to protect your periodontal tissue (gums), for it serves to guard your teeth, your oral health, and your overall health - besides preventing painful infection in your gum tissue itself. When you are experiencing gum problems, maybe despite your best efforts at good oral hygiene at home, it's time to see your periodontist to talk about possible periodontal treatments.
Over the years, even with those who faithfully keep up a regular, proper oral hygiene regimen, gum line recession can gradually creep up on you until it suddenly becomes a noticeable problem.
That said, unhealthy gums are much more prone to recede, and good dental hygiene at home and regular periodontal check ups do much to reduce your risk.
