"...wounding, scarring, and breakage of canine teeth are common; these are evidence of direct physical confrontations during the breeding season."

"Given the frequency of broken teeth, wounding, and facial scarring among competing males (Polar bears)".

Here's David Attenborough stating at 1:39 that bloody battles between polar bears are common.

[Montezuma]

"At least 308 bears were reported killed in conflict situations during this period. Types of conflicts included: encounters (36%), livestock and sea otter depredation (32%), material loss (18%), bear attacks (11%) and garbage (3%)." ~ Kamchatka Brown bears

According to Doug and Dr. Andrea grizzlies often have scars after fights.

"INTRA-SPECIFIC AGGRESSION, OR BEARS KILLING BEARS, WAS THE PRIMARY CAUSE OF DEATH IN BOTH AREAS."

Grizzly bear kills another male grizzly in Yellowstone.
On October 7, 2019, at 0730 hours, a large male grizzly bear was observed feeding on a two- to three-year-old male bear in brush and downfall adjacent to the East Entrance Road. The large male grizzly bear scavenging the carcass was wearing a radiocollar. Telemetry indicated the scavenging bear was adult male Grizzly Bear #791. The dead bear’s zygomatic arches were crushed and there were large canine punctures to both dorsal orbits. The subadult’s mandible articulations were also crushed. The dead bear had multiple bites with 65- 75 mm canine widths on the head and down the dorsal back with associated subcutaneous hemorrhages.

This is bear #791

4 Eurasian brown bears died due to fighting in Spain from 1998-2018. pubmed.ncbi.nlm.nih.gov/32878324/

I got these from Dinopethicus and Warsaw.

According to Scott McMillion grizzlies oftenly fight each other.

More information.....

"Scars are typically found around the head and neck region of male bears; this is where they generally bite one another while they fight."

"Male bears are apt to have scars on heads, necks and front quarters. Lacerated ears and sometimes broken jaws from alterarctions are easy to spot".

"Males rarely reach their 20s, one possible reason is that bears frequently injuried in fights during mating seasons, and over the years these fights take their toll".

This is for those misconceptions redeeming polar bears as very gentle animals.

"Sub adult males lack fighting scars, but mature male bears wear many scars as reminders of many battles over pro - spective mates".

"Wounding may be more common in Polar bears than other bears; fight over females result in wounding, scarring, broken limb, teeth and jaws; some bear limp off and some die of injuries; I have seen a bear with punctured eye due to fight; males who fight intensely show very much broken canines mostly in 14 years old individuals; serious jaw and gums injuries are common and while molars are barely broken but missing of incisors and canines is common; before 7 years bears don't show scars and in old age of 16 it decreases; over life time, male polar bears wear an impressive number of scars which makes them easier to be recognized than females; scars cover all of the body, neck, head and front area; I (the author) have seen a bear with 6 inch deep and 20inch long scar extending from back due belly due to a fight and it was so serious that the lower ribs were visible under a thin layer of muscle but still the tough bear was in good condition and was healing too".
