I had my retainers on in my sleep they broke (the metal part) and I think I swallowed a tiny piece of the metal.
Yes, you will. Here is the chronological order of the MGS games. MGS3 MGS Peace Walker MGS5 MG MG2 MGS1 MGS2 MGS4 I did NOT list any spin-offs.
Metal Gear Solid 5 is technically two games. Ground Zeroes (the prologue) is set in 1975, a year after Peace Walker. The Phantom Pain (the actual game - Guns Of Patriots is another) is set in 1984, 11 years before Metal Gear. Just play Metal Gear Solid, Metal Gear Solid 2, Metal Gear Solid 3 (Peace Walker), and Metal Gear Solid 4.
